[jira] [Commented] (HBASE-11352) When HMaster starts up it deletes the tmp snapshot directory, if you are exporting a snapshot at that time the job will fail

Ted Yu commented on HBASE-11352:
--------------------------------

{code}
+  private static final String SNAPSHOT_INPROGRESS_EXPIRATION_MILLIS_KEY = 
+          "hbase.snapshot.inProgress.expiration.timeMillis";
{code}
Expiration would be measured in days. Maybe use different unit for the above config ?

There're long lines in the patch - line length should be 100 or shorter.

> 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.
