being formatted
                 Key: HDFS-3840
                 URL: https://issues.apache.org/jira/browse/HDFS-3840
             Project: Hadoop HDFS
          Issue Type: Improvement
    Affects Versions: QuorumJournalManager (HDFS-3077)

I started 3 JournalNodes for the first time. Then I formatted the NN. The JournalNodes, log
the following error backtrace:

Seems like we should not log this backtrace in this startup scenario? When I read it, I was
confused and thought there might have been a problem, but the JN was formatted fine.
