Automatic failover support for NN HA
------------------------------------
Key: HDFS-3042
URL: https://issues.apache.org/jira/browse/HDFS-3042
Project: Hadoop HDFS
Issue Type: New Feature
Components: ha, name-node
Reporter: Todd Lipcon
Assignee: Todd Lipcon
HDFS-1623 was the umbrella task for implementation of NN HA capabilities.
However, it only focused on manually-triggered failover.
Given that the HDFS-1623 branch will be merged shortly, I'm opening this JIRA
to consolidate/track subtasks for automatic failover support and related
improvements.
