-------------------------------------------
Summary: Persistent IllegalReferenceCountException at scanner open
Key: HBASE-25698
URL: https://issues.apache.org/jira/browse/HBASE-25698
Project: HBase
Issue Type: Bug
Affects Versions: 2.4.2
Reporter: Andrew Kyle Purtell
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.
