churro morales created HBASE-11352:
--------------------------------------

             Summary: When HMaster starts up it deletes the tmp snapshot directory, if you
are exporting a snapshot at that time the job will fail
                 Key: HBASE-11352
                 URL: https://issues.apache.org/jira/browse/HBASE-11352
             Project: HBase
          Issue Type: Bug
    Affects Versions: 0.94.19
            Reporter: churro morales


We are exporting a very large table.  The export snapshot job takes 7+ days to complete. 
During that time we had to bounce HMaster.  When HMaster initializes, it initializes the SnapshotManager
which subsequently deletes the .tmp directory.

If this happens while the ExportSnapshot job is running the reference files get removed and
the job fails.

Maybe we could put some sort of token such that when this job is running HMaster wont reset
the tmp directory.
