Bikas Saha updated MAPREDUCE-4345:
----------------------------------
Assignee: Bikas Saha
Assigning to myself since this looks like something that follows directly after
MAPREDUCE-4326 and design/implementation would be closely related with it.
> ZK-based High Availability (HA) for ResourceManager (RM)

> Key: MAPREDUCE-4345

> One of the goals presented on MAPREDUCE-279 was to have high availability.
> One way that was discussed, per Mahadev/others on
> https://issues.apache.org/jira/browse/MAPREDUCE-2648 and other places, was ZK:
> {quote}
> 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
> have a HA soln with ZK.
> {quote}
> 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.
