[jira] [Commented] (FLUME-490) mismatch between hadoop versions
causes flume to break silently
[ https://issues.apache.org/jira/browse/FLUME-490?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13169588#comment-13169588 ]
Thomas Vachon commented on FLUME-490:
-------------------------------------
I'm seeing this in 0.9.4 as well. Unfortunetly AWS has Hadoop 0.20.250 (Apache not Cloudera) and I get client = 63, server = 61

> 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.
