Subject [jira] [Created] (HDFS-4233) NN keeps serving even after no journals started while rolling edit
Date Wed, 28 Nov 2012 21:03:58 GMT
Kihwal Lee created HDFS-4233:
--------------------------------

             Summary: NN keeps serving even after no journals started while rolling edit
                 Key: HDFS-4233
                 URL: https://issues.apache.org/jira/browse/HDFS-4233
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: name-node
    Affects Versions: 0.23.5
            Reporter: Kihwal Lee
            Priority: Critical


We've seen namenode keeps serving even after rollEditLog() failure. Instead of taking a corrective
action or regard this condition as FATAL, it keeps on serving and modifying its file system
state. No logs are written from this point, so if the namenode is restarted, there will be
data loss.
