[jira] [Comment Edited] (HBASE-25698) Persistent
IllegalReferenceCountException at scanner open
[ https://issues.apache.org/jira/browse/HBASE-25698?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17309198#comment-17309198 ]

----------------------------------------------------------------
[~apurtell] You had offheap read path (hbase.bucketcache.ioengine) enabled for HBase 2 cluster in this test?
Just going through HBASE-21957 and HBASE-22211 to understand this path better but both are sub-tasks of HBASE-21879 (reading block to bytebuffer instead of byte to reduce young GC)

> Project: HBase
> Issue Type: Bug
> Components: HFile, Scanners
> Affects Versions: 2.4.2
> Reporter: Andrew Kyle Purtell
> Priority: Major
> Fix For: 3.0.0-alpha-1, 2.5.0, 2.4.3

> Persistent scanner open failure. 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. Sink schema settings bloom=ROW encoding=FAST_DIFF compression=NONE.
