Subject [jira] [Commented] (YARN-3039) implement ATS writer service discovery
Date Tue, 13 Jan 2015 01:10:34 GMT

    [ https://issues.apache.org/jira/browse/YARN-3039?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14274538#comment-14274538
] 

Robert Kanter commented on YARN-3039:
-------------------------------------

We should look into using YARN-913's Yarn Service Registry for this, assuming it doesn't require
an external ZooKeeper to be setup; at the very least, we should reuse Curator/ZooKeeper code
from it if possible.

> Per design in YARN-2928, implement ATS writer service discovery. This is essential for
off-node clients to send writes to the right ATS writer. This should also handle the case
of AM failures.
