[jira] [Created] (HADOOP-8279) Auto-HA: Allow manual failover to be
invoked from zkfc.
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
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.
