Jonathan Hsieh created HBASE-7651:
-------------------------------------
Summary: RegionServerSnapshotManager does not accept subsquent
snapshots if previous fails with NotServingRegionException.
Key: HBASE-7651
URL: https://issues.apache.org/jira/browse/HBASE-7651
Project: HBase
Issue Type: Sub-task
Components: snapshots
Affects Versions: hbase-7290
Reporter: Jonathan Hsieh
Priority: Blocker
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)
