Deadlock in HRegion.batchUpdate
-------------------------------
Key: HBASE-952
URL: https://issues.apache.org/jira/browse/HBASE-952
Project: Hadoop HBase
Issue Type: Sub-task
Affects Versions: 0.19.0
Reporter: Jim Kellerman
Assignee: Jim Kellerman
Priority: Blocker
Fix For: 0.19.0
{code}
public void batchUpdate(BatchUpdate[] bus, Integer[] locks)
{code}
Takes out splitsAndClosesLock before calling checkResources. If checkResources
stalls waiting for a cache flush, and a split starts before the flush,
HRegion.close deadlocks when it tries to acquire splitsAndClosesLock
This never resolves because batchUpdate is waiting for a flush that will never
happen since close has already disabled them.
