[jira] [Resolved] (MAPREDUCE-3053) YARN Protobuf RPC Failures in RM
[ https://issues.apache.org/jira/browse/MAPREDUCE-3053?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Chris Riccomini resolved MAPREDUCE-3053.
----------------------------------------
Resolution: Fixed
Fixed with:
val rmAddress = NetUtils.createSocketAddr(conf.get(YarnConfiguration.RM_SCHEDULER_ADDRESS, YarnConfiguration.DEFAULT_RM_SCHEDULER_ADDRESS))
See comment as to why.
