Subject [jira] Created: (HBASE-2634) Clean up and document locks in HRegion
Date Mon, 31 May 2010 05:45:37 GMT
Clean up and document locks in HRegion

                 Key: HBASE-2634
                 URL: https://issues.apache.org/jira/browse/HBASE-2634
             Project: HBase
          Issue Type: Improvement
          Components: regionserver
            Reporter: Todd Lipcon

HRegion now has four different lock objects:
- splitsAndClosesLock (RWLock)
- newScannerLock (RWLock)
- updatesLock (RWLock)
- splitLock (Object)

It's not well documented what the purpose of each is, and I imagine we may be able to get
rid of at least one.
