Tom White commented on YARN-1029:
---------------------------------
Implementing ActiveStandbyElector sounds like a good approach, and the patch is
a good start. From a work sequencing point of view wouldn't it be preferable to
implement the standalone ZKFC first, since it will share a lot of the code with
HDFS (i.e. implement the equivalent of DFSZKFailoverController)?

> It should be possible to embed common ActiveStandyElector into the RM such
> that ZooKeeper based leader election and notification is in-built. In
> conjunction with a ZK state store, this configuration will be a simple
> deployment option.
