Description

If there's a mismatch between hadoop versions on the agents and hdfs flume writes to, flume stops working. This is the log message that tipped us off:

"2011-01-31 05:33:21,748 INFO com.cloudera.flume.handlers.debug.InsistentAppendDecorator: append attempt 122 failed, backoff (60000ms): Protocol org.apache.hadoop.hdfs.protocol.ClientProtocol version mismatch. (client = 61, server = 62)"

Maybe this should be an ERROR instead of INFO statement.
