[jira] Resolved: (HBASE-2097) Deadlock between HRegion.put and
HRegion.close
[ https://issues.apache.org/jira/browse/HBASE-2097?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Jean-Daniel Cryans resolved HBASE-2097.
---------------------------------------
Resolution: Fixed
Assignee: stack
Hadoop Flags: [Reviewed]
I also tried the patch a couple of times and the deadlock is gone. I'm committing the patch to branch plus I removed some annoying debug (MemStoreScanner) that was also added in HBASE-2037.

> HBASE-2037 added a bunch of fixes but also a deadlock:
> HRegion.put:
> {code}
> splitsAndClosesLock.readLock().lock();
> newScannerLock.writeLock().lock();
> {code}
> HRegion.close
> {code}
> newScannerLock.writeLock().lock();
> try {
> splitsAndClosesLock.writeLock().lock();
> {code}
> To recreate, start a PerformanceEvaluation on standalone and it happens roughly 75% of the time.
