  1. #51

    Default LAL 6.1.38 (Compatible with LAE 6.1.x) and LAL 6.0.38 (Compatible with LAE 6.0.x)

    Hi all,

    New in LAL 6.1.38 / LAL 6.0.38

    • The Lavastorm Get for Salesforce node
    • The HTTP node enhancement
    • The K-means Advisor node enhancement
    • The K-means Clustering node enhancement
    • The R Library Package Download node enhancement

    Details of New Functionality

    The Lavastorm Get for Salesforce node queries SALESFORCE.COM objects via SOQL over the SALESFORCE.COM REST API. We recommend all new graphs use the “Lavastorm Get for Salesforce” node instead of the existing “Lavastorm Query for Salesforce” node which has been deprecated. The “Lavastorm Query for Salesforce” node will continue to operate for existing graphs.

    The HTTP node has been enhanced to now include two “Truststore” parameters. These parameters enable the node to utilize a user specified Java Runtime Environment (JRE) trust store. LAL-4928

    The K-Means Advisor node has been enhanced with a new “TransformData” parameter which provides the option to apply z-score standardization to each field in the input data. LAL-2306

    The K-Means Clustering node has been enhanced with a new “TransformData” parameter which provides the option to apply z-score standardization to each field in the input data. LAL-2217

    The R Library Package Download node has been amended to use our own repository https://lavastorm.exavault.com/p/LavastormStatRepo. This is due to compatibility issues with packages distributed on the official CRAN sites. Users of the R Library Package Download node do not need to do anything different. Users of the Power R node, who do not have the R Library Package node, are expected to use the above location in line with the install.packages command and save the libraries to <LAE temp directory>/TERR/libs/. The Lavastorm repository does not currently support linux distributions. The source files can be viewed here LAL-5379

    Experimental Nodes
    WARNING: A range of experimental nodes have been included with the LAE product that streamline a range of common data acquisition, preparation and analysis tasks, particularly for business users.

    Default LAL 6.1.41 (Compatible with LAE 6.1.x) and LAL 6.0.41 (Compatible with LAE 6.0.x)

    Hi all,

    New in LAL 6.1.41 / LAL 6.0.41

    Overview
    • The Cleanse String node enhancement
    • The Data Converter node (Experimental)
    • The Lavastorm Get / Metadata / Update for Salesforce node enhancement
    • The Select Fields node enhancement
    • The Spark Download node (Experimental)
    • The Spark End Session node (Experimental)
    • The Spark Java Submit node (Experimental)
    • The Spark Sort node (Experimental)
    • The Spark Start Session node (Experimental)
    • The Spark Upload node (Experimental)

    Details of New Functionality

    The Cleanse String node has an improved performance. LAL-5643
    The Data Converter node converts the data type of each field based on the discovered data type.
    The Lavastorm Get / Metadata / Update for Salesforce nodes now support the use of a Proxy server. LAL-5556 / LAL-5557 / LAL-5558.
    The Select Fields node has an improved performance. LAL-5644
    The Spark Download node downloads data in the Avro file format from a Spark cluster.
    The Spark End Session node ends a Spark session.
    The Spark Java Submit node provides an interface with a Spark cluster to execute a Spark application.
    The Spark Sort node sorts data in the Avro file format using a Spark cluster.
    The Spark Start Session node starts a Spark session.
    The Spark Upload node uploads data to a Spark cluster in the Avro file format.

    Bugfixes
    The Output Excel and Append Excel nodes now cater for dates greater than the year 2098. LAL-5563
    The Change Metadata node now caters for dates greater than the year 2098. LAL-5507

    Third party known issues/considerations
    • The Avro 1.7.7 specification calls out some constraints on the metadata that it can support. Specifically it places restrictions on the names of fields:
      The Field names must:
      start with [A-Za-z_]
      subsequently contain only [A-Za-z0-9_]
    • Avro 1.7.7 does not support date, time and datetime data types. As a result if you wish to upload data and use the Lavastorm nodes then these fields will need to be converted to string.

    See the release notes for more details. the Release notes and download can be found on our download page.

    Example graphs attached for the Spark based nodes. Please read the Spark Configuration v0.1.pdf before attempting to run the nodes.

    Default LAL 6.1.45 (Compatible with LAE 6.1.x) and LAL 6.0.45 (Compatible with LAE 6.0.x)

    Hi all,

    New in LAL 6.1.45 / LAL 6.0.45

    Overview
    Please Note: All of the Spark nodes now require Spark 1.5.0 as a minimum in the <LAE Install>/lib/java/lal/spark directory. In addition the Spark SQL Query node requires the Hive Client Configuration to be located on the laeServer machine. (See the Spark Configuration Guide for Lavastorm.pdf included in your installed documentation).
    • The Archive Compress node
    • The QVD File node
    • The Spark SQL Query node (Experimental)
    • The Spark Agg node enhancement
    • The Spark Join node enhancement
    • The Excel File node enhancements

    Details of New Functionality
    The Archive Compress node creates a compressed archive file containing one or more files. LAL-4961
    The QVD File node imports data from a QVD file. LAL-3102. Additional software libraries are required in order for this node to work (commons-io-2.4.jar, irbi-fileutils-0.1.0.jar, jdbm-3.0-SNAPSHOT.jar, qvd-converter-core-1.5.0.jar and qvd-reader-1.5.0.jar).
    Please contact Ralf Becher using the contact details below in order to purchase these libraries. Once you have those libraries they need to be saved to <LAE install Directory>/lib/java/lal.
    IT Beratung Ralf Becher
    Leipzig, Germany
    ralf.becher@web.de

    The Spark SQL Query node provides an interface with a Spark cluster to execute a Spark SQL query. LAL-6194
    The Spark Agg node has new parameters included to allow customers to include or exclude fields from the aggregate function. LAL-5817
    The Spark Join node has been enhanced to include new parameters so that users are able to filter on one or both datasets. LAL-6001
    The Excel File node has a new parameter called IgnoreCellFormatting which allows the raw data underneath cell formatting to be imported to LAE. The default behavior is set to “Ignore” to allow for backwards compatibility. LAL-1554/gnats 5119

    Bugfixes
    The Trim Fields node now fully caters for fields with or without single quotes. LAL-5004
    The Trim Fields node set to NULL if empty option has been improved to work on all fields. Also if the field names do not exist for the excluded/included option an exception is now returned. LAL-4049

    Third party known issues/considerations
    The Spark SQL Query node has highlighted some Apache issues with the following scenarios:
    • Selecting a field with binary type fails with the exception “UnresolvedUnionException: Not in union ["bytes","null"]”. This is already raised on Apache JIRA: https://issues.apache.org/jira/browse/AVRO-1401
    • Describe operation returns 3 fields (col_name, col_type, comment) however the comment field is handled as not “nullable” but returns a NULL value.

    The Spark SQL Query node processes against Hive tables. When Hive tables are processed by the cluster, the minimum memory requirement is higher compared with the memory required to run other Spark nodes that do not access Hive. The DriverMemory and ExecutorMemory both have a minimum 5G threshold. Users are advised to increase this for larger environments.


    New in LAL 6.1.44 / LAL 6.0.44

    Overview
    Please Note: All of the Spark nodes now require Spark 1.5.0 as a minimum in the <LAE Install>/lib/java/lal/spark directory (See the Spark Configuration Guide included in your installed documentation).
    • The SharePoint 2010 suite of nodes enhancements
    • The Spark Agg node enhancements
    • The Spark Filter node enhancements
    • The Spark Java Submit node enhancement
    • The Spark Join node enhancement
    • New Guides included

    Details of New Functionality
    The SharePoint 2010 suite of nodes have been enhanced to disable Forms Based Authentication. LAL-5739
    The SharePoint 2010 suite of nodes have been enhanced to support situations where there is a URL-Folder Name mismatch. Please note: If there is a mismatch then additional processing is required to match up display names with underlying names used by the API. LAL-5623
    The Spark Agg node has been enhanced to include the function name in the output columns. LAL-6112
    The Spark Agg node now includes grouping functionality. Users are able to group aggregated data by one or more fields so that any records with identical values in the specified group fields are combined into a single record. LAL-5818
    The Spark Filter node now allows a user to specify which fields are to be included or excluded on the output file(s). LAL-5814
    The Spark Filter now includes the ability to filter on an additional two sets of filter criteria. LAL-5813
    The Spark Java Submit node has a new parameter called SparkAssemblyJar. Users are now able to specify the JAR they wish the Spark application to execute with. Users are advised to review the ‘Spark Configuration Guide for Lavastorm.pdf’ located in their LAE installation. LAL-6075
    The Spark Join node now allows the ability to select from an additional four join types (default join type ‘Inner’): Left Outer, Right Outer, Full Outer, Left Semi. LAL-5998
    Three new documents have been added to the install of LAL. The documents included are: ‘CRAN Package Install Guide for Lavastorm.pdf’, ‘Spark Configuration Guide for Lavastorm.pdf’ and ‘SSL Connections Guide for Lavastorm.pdf’. LAL-6111
    LAL V6.1.45 Release Notes © Lavastorm Analytics 2016 All Rights reserved Page 17

    Known issues/considerations
    • The Spark Sample node has been updated to return ‘N Records’ instead of ‘First N Records’. When using the 'N records' option, the order of the generated sample set is not guaranteed to reflect the order of the data in the input file(s).

    Default LAL 6.1.48 (Compatible with LAE 6.1.x)

    Hi All,

    LAL 6.1.48 (Compatible with LAE 6.1.x) is now available.

    New in LAL 6.1.48

    Overview
    • Data Converter node GA
    • Spark Agg node enhancement
    • Spark nodes Kerberos keytab authentication enhancement
    • Spark Download and Spark Data Viewer string data type enhancement
    • Spark nodes delimited file support enhancements
    • Spark nodes GA


    Details of New Functionality
    The status of the (previously Experimental) Data Converter node has now been changed from experimental to fully supported.

    The Spark Agg node now outputs a GroupBy field when the field is also included in an aggregation function. LAL-6480

    The Spark nodes have been enhanced to offer an additional Kerberos authentication method which uses a secure keytab file.

    The Spark Download node and Spark Data Viewer node have been enhanced to enable the customer to specify whether string fields should be output as unicode field type (default) or as string field type. LAL-6870
    A number of Spark nodes have been enhanced to allow customers to specify a delimited file as the node’s input data source instead of the default Avro file format. Configuration options enable the customer to specify: the delimiter character, whether the delimited file has a header record, the quote character, the escape character and whether empty strings are to be considered NULL values. By default, the nodes attempt to automatically identify the schema. The schema can also be explicitly defined. LAL-6805, LAL-6697

    The status of the (previously Experimental) Spark nodes has now been changed from experimental to fully supported. This relates to the following nodes: Spark Start Session, Spark End Session, Spark Upload, Spark Download, Spark Data Viewer, Spark Agg, Spark Filter, Spark Join, Spark Sample, Spark Sort, Spark SQL Query.

    Bugfixes
    Some extraneous parameters are no longer visible on the JSON Data node and the Logistic Regression Diagnostics node. LAL-6523, LAL-6840
    Duplicate help text was removed from the Spark SQL Query node’s help information. LAL-6797

    Removed Functionality
    The following experimental nodes have been removed from the installation:
    • Complex Lookup
    • Date Range Lookup
    • String Based Lookup


    Third party known issues/considerations

    In the situation where a Spark node is configured to import data from a delimited file and the schema has been defined by the user, the schema must be valid. When the schema is invalid the node execution may complete successfully but no records will be output.

    The Release Notes and installers can be found on our download page.

    Regards,
    Adrian
