[jira] [Created] (HDFS-2190) NN fails to start if it encounters an empty or malformed fstime file

NN fails to start if it encounters an empty or malformed fstime file
--------------------------------------------------------------------

                 Key: HDFS-2190
                 URL: https://issues.apache.org/jira/browse/HDFS-2190
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: name-node
    Affects Versions: 0.20.203.0
            Reporter: Aaron T. Myers
            Assignee: Aaron T. Myers


On startup, the NN reads the fstime file of all the configured dfs.name.dirs to determine which one to load. However, if any of the searched directories contain an empty or malformed fstime file, the NN will fail to start. The NN should be able to just proceed with starting and ignore the directory containing the bad fstime file.
