> 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.
