Steve Loughran created HDFS-14060:
-------------------------------------
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
