Subject [jira] [Created] (HDFS-4134) hadoop namenode & namenode entry points should return -1 exit code on bad arguments
Date Thu, 01 Nov 2012 15:37:12 GMT
Steve Loughran created HDFS-4134:
------------------------------------

             Summary: hadoop namenode & namenode entry points should return -1 exit code
on bad arguments
                 Key: HDFS-4134
                 URL: https://issues.apache.org/jira/browse/HDFS-4134
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: name-node
    Affects Versions: 1.0.4
            Reporter: Steve Loughran
            Priority: Minor


When you go  {{hadoop namenode start}} (or some other bad argument to the namenode), a usage
message is generated -but the script returns 0. 

This stops it being a robust command to invoke from other scripts -and is inconsistent with
the JT & TT entry points, that do return -1 on a usage message
