Subject [jira] [Commented] (HADOOP-7505) EOFException in RPC stack should have a nicer error message
Date Wed, 03 Aug 2011 04:33:28 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-7505?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13078579#comment-13078579
] 

Todd Lipcon commented on HADOOP-7505:
-------------------------------------

HADOOP-7346 took care of this for the case of connecting to a newer incompatible server. But,
still doesn't help if you accidentally point at the wrong port (eg the web port instead of
IPC). So, this JIRA could still be an improvement past that.

> Lots of user logs involve a user running mismatched versions, and for some reason or
another, they get EOFException instead of a proper version mismatch exception. We should be
able to catch this at appropriate points, and have a nicer exception message explaining that
it's a possible version mismatch, or that they're trying to connect to the incorrect port.
