Jonathan Hsieh updated HBASE-7651:
----------------------------------
Attachment: hbase-7651.patch
First cut of patch. Need to add unit test. Something very similar to this has
been testing on 20 node cluster for several hours. Not all snapshot succeed but
the snapshotting mechanism no longer gets stuck.
> RegionServerSnapshotManager fails with CancellationException if previous
> snapshot fails in per region task

> I've reproduced this problem consistently on a 20 node cluster.
> The first run fails on a node (jon-snaphots-2 in this case) to take snapshot
> due to a NotServingRegionException (this is acceptable)
