churro morales resolved HBASE-11352.
------------------------------------
Resolution: Not A Problem
In newer versions of HBase you can just select the skipTmp option when
Exporting Snapshots this will resolve this issue.
> When HMaster starts up it deletes the tmp snapshot directory, if you are
> exporting a snapshot at that time the job will fail

> 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.
