URL: https://issues.apache.org/jira/browse/MAPREDUCE-4345
Project: Hadoop Map/Reduce
Issue Type: Improvement
Reporter: Harsh J

Am not sure, if you already know about the MR-279 branch (the next version of
MR framework). We've been trying to integrate ZK into the framework from the
beginning. As for now, we are just doing restart with ZK but soon we should

There is now MAPREDUCE-4343 that tracks recoverability via ZK. This JIRA is
meant to track HA via ZK.
Currently there isn't a HA solution for RM, via ZK or otherwise.
