[jira] [Commented] (HADOOP-7505) EOFException in RPC stack should have a nicer error message

["Kihwal Lee (Commented) (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HADOOP-7505?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13147109#comment-13147109 ] 

Kihwal Lee commented on HADOOP-7505:
------------------------------------

In branch-0.20-security, I've seen clients getting an EOFException when the connection was closed in the middle of an RPC transaction. I am guessing this is because the input stream was broken while reading a response. It makes a perfect sense at that level, but showing that to users who are reading a file can be quite confusing. I haven't checked whether the trunk also has this issue.

> 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.
