Subject [jira] [Reopened] (YARN-1028) Add FailoverProxyProvider like capability to RMProxy
Date Fri, 20 Dec 2013 19:38:15 GMT

     [ https://issues.apache.org/jira/browse/YARN-1028?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Karthik Kambatla reopened YARN-1028:
------------------------------------


Reopening to fix a bug in RMProxy (YARN-1028) - the number of failovers should be tuned, not
the policy. I thought I tested this on a cluster, but looks like I forgot to remove yarn.client.failover-max-attempts
from the config.

> RMProxy layer currently abstracts RM discovery and implements it by looking up service
information from configuration. Motivated by HDFS and using existing classes from Common,
we can add failover proxy providers that may provide RM discovery in extensible ways.
