> Came as part of review discussion in HBASE-15554. If there are references
> kept to previous cells in the read path, with the Ref count based eviction
> mechanism in trunk, then chances are there to evict a block backing the
> previous cell but the read path still does some operations on that garbage
> collected previous cell leading to incorrect results.
> Areas to target
> -> Storescanner
> -> Bloom filters (particularly in compaction path)
> Thanks to [~anoop.hbase] to point out this in bloomfilter path. But we found
> it could be in other areas also.
