[ https://issues.apache.org/jira/browse/HBASE-24788?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Sean Busbey reopened HBASE-24788: --------------------------------- this change broke source compatibility by removing the throws for {{InterruptedException}} from the {{getRecordWriter}} and {{checkOutputSpecs}} methods of {{TableOutputFormat}}. I don't see any discussion of doing so, so I am guessing it was an oversight. Normally we don't allow these kinds of changes in maintenance or minor releases. [~te...@apache.org], [~vjasani], and [~bharathv]: please fix for at least branch-1, branch-2, branch-2.3, and branch-2.2. If you want to keep the removal for master please flag the change as incompatible and release note it apparently. > Fix the connection leaks on getting hbase admin from unclosed connection > ------------------------------------------------------------------------ > > Key: HBASE-24788 > URL: https://issues.apache.org/jira/browse/HBASE-24788 > Project: HBase > Issue Type: Bug > Components: mapreduce > Affects Versions: 3.0.0-alpha-1, 2.3.0, 1.6.0 > Reporter: Sandeep Pal > Assignee: Sandeep Pal > Priority: Major > Fix For: 3.0.0-alpha-1, 2.3.1, 1.7.0, 2.4.0, 2.2.7 > > > Observed the significant increase in ZK connection on performance testing on > map reduce jobs.
