[jira] Updated: (HADOOP-1071) RPC$VersionMismatch exception is not
fatal to JobTracker
Posted by "Tahir Hashmi (JIRA)" <ji...@apache.org>.

Tahir Hashmi updated HADOOP-1071:
---------------------------------
Attachment: 1071.patch
Patch for fixing HADOOP-1071. Apart from fixing the retry issue, I've also changed the log level to fatal in JobTracker.main's exception handler.
Tested the patch on a single-node setup. JT now dies with a message similar to the one below:
2007-03-14 23:45:29,572 FATAL org.apache.hadoop.mapred.JobTracker: org.apache.hadoop.ipc.RPC$VersionMismatch: Protocol org.apache.hadoop.dfs.ClientProtocol version mismatch. (client = 99, server = 9)
at org.apache.hadoop.ipc.RPC.getProxy(RPC.java:252)
