Description
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. Sink schema settings bloom=ROW encoding=FAST_DIFF compression=NONE.
