Todd Lipcon updated HDFS-2291: ------------------------------ Attachment: hdfs-2291.txt Attached patch adds a thread to the SBN which takes checkpoints. It doesn't currently deal with the case where a checkpoint is happening while the SBN needs to become active. I'm working on that now, but figured I'd put this patch up for early review. This depends on HDFS-2716. > HA: Checkpointing in an HA setup > -------------------------------- > > Key: HDFS-2291 > URL: https://issues.apache.org/jira/browse/HDFS-2291 > Project: Hadoop HDFS > Issue Type: Sub-task > Components: ha, name-node > Affects Versions: HA branch (HDFS-1623) > Reporter: Aaron T. Myers > Assignee: Todd Lipcon > Fix For: HA branch (HDFS-1623) > > Attachments: hdfs-2291.txt > > > We obviously need to create checkpoints when HA is enabled. One thought is to > use a third, dedicated checkpointing node in addition to the active and > standby nodes. Another option would be to make the standby capable of also > performing the function of checkpointing. -- This message is automatically generated by JIRA.
