Important changes and enhancements

Platform updates:

  • Big Match now supports Hortonworks Data Platform 3.1.5.0 with Ambari 2.7.5 along with Hortonworks Data Platform 2.6.5 with Ambari 2.6.2.
    Note: Disable the Phoenix query server in the HBASE service before installing Big Match on HDP 3.1.x

New features and enhancements:

  • This release introduces the ability to publish IBM InfoSphere MDM Standard Edition Entities/Composite Views from MDM Publisher and the ability to view and search them in IBM Entity Insight.

  • This release enhances the Big Match Publish-to-Graph workflow, adding the ability to publish Entities/Composite Views from Big Match to Entity Insight.

  • The Big Match Extract Entities workflow can now extract to CSV.

Known issues for Big Match:

  • In HDP 3.1.x, Spark bulk jobs like Bucket Analysis and Token Frequency Analysis, or other analysis jobs, might fail when launched the first time but succeed subsequently. This is a known issue with Oozie/Spark. The curator library shipped with Oozie interferes at times with the same library shipped with Spark. (#1357)
  • Logging in to the sample PME Search application fails randomly at times. To resolve this issue, clear your cookies and browser cache and then log in again. (#1369)
  • Uninstalling Big Match does not clean up the Ambari database. Manual steps are required before re-installing Big Match. For more information, see the Big Match documentation in IBM Knowledge Center. This is a known issue with Ambari.

Known issues and limitations for Entity Insight:

  • Records created while a match is running will result in the new record not linking with other records.
  • Global Entity Statistics (on the upper-left corner of the user interface) do not auto-refresh and can be refreshed by clicking the refresh button.
  • When Golden Records/Entities/Composite views are published by MDM Publisher to Entity Insight, Publisher does not trigger any matching in Entity Insight as the data being published is already de-duplicated/resolved entities and when more data has to be landed into Entity Insight, the base repository data will need to be matched and the trigger to matching the base data will depend on where the data is coming from. For more information, see the Big Match documentation in IBM Knowledge Center.

Defects fixed in this release:

  • Security fixes are included in this release of Big Match.
  • Derive attempts fail on records with malformed data. For more information about how to enable this configuration (optionally), see the Big Match documentation in IBM Knowledge Center.

  • Uninstalling Big Match 11.5.0.10 does not clean up the Big Match repository in Ambari, resulting in a new installation not working. For more information about how to clean up and install 11.5.0.10, see the Big Match documentation in IBM Knowledge Center.

  • Bulk mode for some workflows were broken in 11.5.0.10 because of a HBase version change. These were fixed in 11.5.0.11.
