> CME in StoreScanner causes region server crash
> ----------------------------------------------
>
> Key: HBASE-20322
> URL: https://issues.apache.org/jira/browse/HBASE-20322
> Project: HBase
> Issue Type: Bug
> Affects Versions: 1.3.2
> Reporter: Thiruvel Thirumoolan
> Assignee: Thiruvel Thirumoolan
> Priority: Major
> Fix For: 1.5.0, 1.3.3, 1.4.4

> Attachments: HBASE-20322.branch-1.3.001.patch,

> RS crashed with ConcurrentModificationException on our 1.3 cluster, stack
> trace below. [~toffer] and I checked and there is a race condition between
> flush and scanner close. When StoreScanner.updateReaders() is updating the
> scanners after a newly flushed file (in this trace below a region close
> during a split), the client's scanner could be closing thus causing CME.
> Its rare, but since it crashes the region server, needs to be fixed.
