Subject [jira] Created: (HDFS-1258) Clearing namespace quota on "/" corrupts FS image

Clearing namespace quota on "/" corrupts FS image

                 Key: HDFS-1258
                 URL: https://issues.apache.org/jira/browse/HDFS-1258
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: name-node
            Reporter: Aaron T. Myers

The HDFS root directory starts out with a default namespace quota of Integer.MAX_VALUE. If
you clear this quota (using "hadoop dfsadmin -clrQuota /"), the fsimage gets corrupted immediately.
Subsequent 2NN rolls will fail, and the NN will not come back up from a restart.
