HA: Allow saveNamespace operations to be canceled
-------------------------------------------------
Key: HDFS-2507
URL: https://issues.apache.org/jira/browse/HDFS-2507
Project: Hadoop HDFS
Issue Type: Improvement
Components: name-node
Affects Versions: HA branch (HDFS-1623), 0.23.0
Reporter: Todd Lipcon
For HDFS-2291 (checkpointing in HA setup) we need to allow the StandbyNode to
handle a failover while it may be in the middle of saving a checkpoint. This
implies that checkpoints need to be abortable.
This JIRA is to implement this functionality. Even though this is only needed
for HA, I think we should do the infrastructure in trunk to simplify future
merges.
