> The problem is that when the snapshot occurs TimeoutException  or other Exceptions, there
is no correct delete /hbase/.hbase-snapshot/tmp, which causes the cleanerChore to fail to
complete the archive correctly.
> Modifying the configuration parameter (hbase.snapshot.master.timeout.millis = 600000)
only reduces the probability of the problem occurring.
> So the solution to the problem is: multi-Threaded exceptions or TimeoutExceptions, the
Main-thread must wait until all the tasks are finished or canceled, the Main-thread can be
cleared /hbase/.hbase-snapshot/tmp/snapshotName.Otherwise the task is likely to write /hbase/.hbase-snapshot/tmp/snapshotName/region
- mainfest
> The problem exists in disabledTableSnapshot and enabledTableSnapshot, because I'm currently
using the disabledTableSnapshot, so I provide the patch of disabledTableSnapshot
