-------------------------------------
Summary: Prevent regions from moving during online snapshot.
Key: HBASE-7735
URL: https://issues.apache.org/jira/browse/HBASE-7735
Project: HBase
Issue Type: Sub-task
Reporter: Jonathan Hsieh
To increase the probability of snapshots succeeding, we should attempt to
prevent splits and region moves from happening. Currently we take region locks
but this could be "too late" and results in an aborted snapshot.
We should probably take the table lock (0.96) when starting a snapshot and for
a 0.94 backport we should probably disable the balancer.
This will probably not be tackled until after trunk merge.
