>             Project: HBase
>          Issue Type: Bug
>    Affects Versions: 2.0.0
>            Reporter: Heng Chen
>            Assignee: Heng Chen
>            Priority: Major
>             Fix For: 2.0.0
>         Attachments: HBASE-16490.patch, HBASE-16490.v1.patch, 
> HBASE-16490.v2.patch
> 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.
