Mikhail Antonov updated HBASE-18397: ------------------------------------ Fix Version/s: (was: 1.3.2) 1.3.3 > StoreFile accounting issues on branch-1.3 and branch-1 > ------------------------------------------------------ > > Key: HBASE-18397 > URL: https://issues.apache.org/jira/browse/HBASE-18397 > Project: HBase > Issue Type: Umbrella > Components: regionserver, Scanners > Affects Versions: 1.3.0 > Reporter: Mikhail Antonov > Fix For: 2.0.0, 1.3.3 > > > 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_): > {quote} > 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} -- This message was sent by Atlassian JIRA (v6.4.14#64029)
