Allen Wittenauer updated HDFS-2507: ----------------------------------- Fix Version/s: (was: 2.0.0-alpha) 0.23.0 > 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: namenode > Affects Versions: HA branch (HDFS-1623), 0.23.0 > Reporter: Todd Lipcon > Assignee: Todd Lipcon > Fix For: 0.23.0 > > Attachments: hdfs-2507.txt > > > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
