Eli Collins updated HADOOP-7938: -------------------------------- Attachment: hadoop-7938.txt Patch attached. Aside from the tests, manually failed over with fencing via hadadmin using sshfence. Will file a jira for passing fromSvc as an argument to the fencing script instead of relying on it being configured, and for being able to use logical dfs.ha.namenode.id instead of rpc addrs. > HA: the FailoverController should optionally fence the active during failover > ----------------------------------------------------------------------------- > > Key: HADOOP-7938 > URL: https://issues.apache.org/jira/browse/HADOOP-7938 > Project: Hadoop Common > Issue Type: Sub-task > Components: ha > Affects Versions: HA Branch (HDFS-1623) > Reporter: Eli Collins > Assignee: Eli Collins > Fix For: HA Branch (HDFS-1623) > > Attachments: hadoop-7938.txt > > > The FailoverController in HADOOP-7924 needs to be able to fence off the > current active in case it fails to transition to standby (or the user > requests it for sanity). This is needed even for manual failover (the CLI > should use the configured fencing mechanism). The FC needs to access the > HDFS-specific implementations HDFS-2179, could add a common fencing interface > (or just shell out but we may not always want to do that). -- This message is automatically generated by JIRA.
