Suresh Srinivas commented on HDFS-2185:
---------------------------------------
Todd, instead of incorporating HDFS-2681 into this, can we finish the ZK
library as a part of that jira and focus this jira on FailoverController.
> HA: ZK-based FailoverController
> -------------------------------

> Key: HDFS-2185
> URL: https://issues.apache.org/jira/browse/HDFS-2185
> Project: Hadoop HDFS
> Issue Type: Sub-task
> Components: ha
> Affects Versions: HA branch (HDFS-1623)
> Reporter: Eli Collins
> Assignee: Todd Lipcon
>
> This jira is for a ZK-based FailoverController daemon. The FailoverController
> is a separate daemon from the NN that does the following:
> * Initiates leader election (via ZK) when necessary
> * Performs health monitoring (aka failure detection)
> * Performs fail-over (standby to active and active to standby transitions)
> * Heartbeats to ensure the liveness
> It should have the same/similar interface as the Linux HA RM to aid
> pluggability.
