[jira] Created: (HBASE-2459) Use finer-grain locking in
HConnectionManager
Use finer-grain locking in HConnectionManager
---------------------------------------------
Key: HBASE-2459
URL: https://issues.apache.org/jira/browse/HBASE-2459
Project: Hadoop HBase
Issue Type: Improvement
Components: client
Reporter: Jonathan Gray
Priority: Critical
Fix For: 0.20.5, 0.21.0
Currently we synchronize within HConnectionManager.locateRegionInMeta() when looking up the cached location (and querying meta if not cached). We use the same lock for every user-space region.
We really only need per-region synchronization here.
