> 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.
