Description

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.
