             Summary: Fix race condition between SnapshotManager and 
SnapshotCleaner
                 Key: HBASE-16490
                 URL: https://issues.apache.org/jira/browse/HBASE-16490
             Project: HBase
          Issue Type: Bug
            Reporter: Heng Chen
             Fix For: 2.0.0


As [~mbertozzi] comments on HBASE-16464,  there maybe race condition between 
SnapshotManager and SnapshotCleaner.  We should use one lock when create 
snapshot,  and cleanup should acquire the lock before take action.

One method is pass HMaster as param into Cleaner through 
{{FileCleanerDelegate.getDeletableFiles}},  suggestions are welcomed.
