             Summary: HDFS fetchdt command to return error codes on success/failure
                 Key: HDFS-14060
                 URL: https://issues.apache.org/jira/browse/HDFS-14060
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: tools
    Affects Versions: 3.3.0
            Reporter: Steve Loughran


The {{hdfs fetchdt}} command always returns 0, even when there's been an error (no token issued, no file to load, usage, etc). This means its not that useful as a command line tool for testing or in scripts.

Proposed: exit non-zero for errors; reuse LaucherExitCodes for these
