Subject Re: Hadoop 2.0.3 namenode issue
Date Fri, 15 Feb 2013 19:01:45 GMT
I don't see a crash log in your snippets. Mind pastebinning the NN
crash log up somewhere? Did both NNs go down?

In any case, the log below is due to a client attempting to connect
with an older HDFS library. This would log such warns (and also
indicate the client IP/attempt port as you notice), but in no case
will it cause an NN crash.
