Subject [jira] Created: (MAPREDUCE-1468) Too many log messages generated if a node has a different Hadoop version installed
Date Tue, 09 Feb 2010 01:29:28 GMT
Too many log messages generated if a node has a different Hadoop version installed
----------------------------------------------------------------------------------

                 Key: MAPREDUCE-1468
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-1468
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
    Affects Versions: 0.20.1
            Reporter: Qi Liu


When upgrading or downgrading Hadoop, for a large cluster it is possible that some nodes are
not upgraded/downgraded. In this case, the jobtracker and namenode generates gigabytes of
logs each day, reporting protocol version mismatch. Such log message is generated once every
3ms.

Ideally, the misbehaved node should quit retrying after several attempts if there is a protocol
version mismatch. At the very least, the log message should be minimized (maybe once a day
or once per start up).
