Deadlock between HRegion.put and HRegion.close
----------------------------------------------
Key: HBASE-2097
URL: https://issues.apache.org/jira/browse/HBASE-2097
Project: Hadoop HBase
Issue Type: Bug
Reporter: Jean-Daniel Cryans
Priority: Blocker
Fix For: 0.20.3
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.
