[jira] [Created] (HADOOP-7938) HA: the FailoverController should
optionally fence the active during failover
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)
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).
