Subject RE: More than one RM in YARN?
Date Wed, 19 Sep 2012 17:05:14 GMT

Could you please elaborate a bit on the use case you are targeting? Do you
want to run multiple active RM's in the cluster? And they are being used
concurrently? Or are you talking about failover scenarios?

Not yet, it is coming:
https://issues.apache.org/jira/browse/MAPREDUCE-4326 should go in first,
followed by the HA work after it via
https://issues.apache.org/jira/browse/MAPREDUCE-4345 (Latter isn't a dupe
of the former exactly).

We're looking at this, and I want to know if there's a standard way to do
it. Are people doing round robin DNS, load balancers, etc? Is it possible
to configure node managers to have a list of RMs rather than a single one?
