Amit Kabra created HBASE-19519:
----------------------------------
Summary: HBase creates snapshot, even after throwing snapshot
creation exception.
Key: HBASE-19519
URL: https://issues.apache.org/jira/browse/HBASE-19519
Project: HBase
Issue Type: Bug
Reporter: Amit Kabra
Example client side flow:
for : i = 0 --> 3 retrials:
a) create snapshot
b) In case of exception catch it and delete snapshot.
c) sleep 1 min * i.
Now #a throws creation exception if creation takes more than 5 mins. Many times
cluster can get busy and snapshot creation takes time and it can happen :
i = 0 --> #a takes time, throws snapshot creation exception --> #b doesn't work
since snapshot isn't created --> #c snapshot got created
i = 1 --> #a gives snapshot exist exception.
Issue : Since creation failed exception came, hbase should delete the snapshot
and should not create it since client won't know that its a valid or a
corrupted snapshot.
