Harsh J created HDFS-4002:
-----------------------------
Summary: Tool-ize OfflineImageViewer and make sure it returns
proper return codes upon exit
Key: HDFS-4002
URL: https://issues.apache.org/jira/browse/HDFS-4002
Project: Hadoop HDFS
Issue Type: Bug
Components: tools
Affects Versions: 2.0.0-alpha
Reporter: Harsh J
Priority: Minor
We should make OfflineImageViewer structured (code-wise) in the same way as
OfflineEditsViewer is. Particularly, OIV must implement the Tool interface, and
must return proper exit codes upon success/failure conditions. Right now, it
returns 0 in both successful parse and unsuccessful ones.
