-----------------------------------
Assignee: Todd Lipcon
> Auto-HA: Allow manual failover to be invoked from zkfc.
> -------------------------------------------------------
>
> Key: HADOOP-8279
> URL: https://issues.apache.org/jira/browse/HADOOP-8279
> Project: Hadoop Common
> Issue Type: Improvement
> Components: ha
> Affects Versions: Auto Failover (HDFS-3042)
> Reporter: Mingjie Lai
> Assignee: Todd Lipcon
> Fix For: Auto Failover (HDFS-3042)
>
>
> HADOOP-8247 introduces a configure flag to prevent potential status
> inconsistency between zkfc and namenode, by making auto and manual failover
> mutually exclusive.
> However, as described in 2.7.2 section of design doc at HDFS-2185, we should
> allow manual and auto failover co-exist, by:
> - adding some rpc interfaces at zkfc
> - manual failover shall be triggered by haadmin, and handled by zkfc if auto
> failover is enabled.
