EOFException in RPC stack should have a nicer error message
-----------------------------------------------------------
Key: HADOOP-7505
URL: https://issues.apache.org/jira/browse/HADOOP-7505
Project: Hadoop Common
Issue Type: Improvement
Components: ipc
Affects Versions: 0.23.0
Reporter: Eli Collins
Priority: Minor
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.
