Subject [jira] [Commented] (MAPREDUCE-6705) Task failing continuously on trunk
Date Fri, 27 May 2016 16:20:13 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-6705?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15304266#comment-15304266
] 

Chris Nauroth commented on MAPREDUCE-6705:
------------------------------------------

Hello [~bibinchundatt].  The exception looks like an incompatibility between client and server
protobuf RPC message definitions.  Can you please share what version of Hadoop is showing
this problem?  Are you running different versions for different components?
