Fixed Issues in Cloudera Search

Review the list of Cloudera Search issues that are resolved in Cloudera Runtime 7.1.7 SP2.

CDPD-46198: jsoup version bumped up to 1.15.3 for fixing the CVE.

CDPD-26082: MapreduceIndexerTool performance problem in CDP

The handling of HDFS caching in MRIT has changed to mitigate this known issue. Before the fix, the solr.hdfs.blockcache.enabled setting was always forced to be false and could not be overridden. After the fix, it becomes possible to control this setting using the solr.hdfs.blockcache.enabled property and its default value has also been changed to true.

This has a few consequences that may affect existing systems:

• MRIT starts to use HDFS caching by default, which may slightly increase memory usage.
• It is possible now to control HDFS caching. For more information, see Solr and HDFS - the block cache in Tuning Cloudera Search.
