> This jira is an umbrella for a set of issues around store file accounting on branch-1.3 and branch-1 (I believe).
> At this point I do believe that many / most of those issues are related to backport of HBASE-13082 done  long time ago. A number of related issues were identified and fixed previously, but some still yet to be debugged and fixed. I think that this class of problems prevents us from releasing 1.3.2 and moving stable pointer to branch 1.3 at this point, so marking as critical.
> Below is overview by Andrew Purtell from dev list: (Subject: _Re: Branch 1.4 update_):

> Let me provide some context.
> The root issue was fallout from a locking change introduced just prior to
> release of 1.3. That change was HBASE-13082. Lars H proposed a change. It
> was committed to trunk but quickly reverted. After the revert Lars decided
> to drop the work rather than fix it for reapplication. However, the work
> was picked up by others and eventually found its way into branch-1, then
> branch-1.3, then 1.3.x releases. There were unintended side effects,
> causing bugs. The umbrella issue HBASE-18397 tracks a bunch of fix work the
> community has done since. The last known bug fix was HBASE-18771, found and
> fixed by our Abhishek. The last known change I know of was work I did on
> HBASE-18786 to remove some dodgy exception handling (prefer aborts to
> silent data corruption). Is this enough to move the stable pointer?
> According to our testing at Salesforce, yes, so far. We have yet to run in
> full production. Give us a few months of that and my answer will be
> unconditional one way or another. According to some offline conversation
> with Mikhail and Gary, the answer is in fact no, they still have one hairy
> use case causing occasional problems that look like more of this, but that
> feedback predates HBASE-18771.{quote}
