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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
