Work on HBASE-25698 started by Viraj Jasani. -------------------------------------------- > Persistent IllegalReferenceCountException at scanner open when using > TinyLfuBlockCache > -------------------------------------------------------------------------------------- > > Key: HBASE-25698 > URL: https://issues.apache.org/jira/browse/HBASE-25698 > Project: HBase > Issue Type: Bug > Components: HFile, Scanners > Affects Versions: 2.4.2 > Reporter: Andrew Kyle Purtell > Assignee: Viraj Jasani > Priority: Major > Fix For: 3.0.0-alpha-1, 2.5.0, 2.4.3 > > > Persistent scanner open failure with offheap read path enabled. > Not sure how it happened. Test scenario was HBase 1 cluster replicating to > HBase 2 cluster. ITBLL as data generator at source, calm policy only. Scanner > open errors on sink HBase 2 cluster later during ITBLL verify phase.
