Jing Zhao created HDFS-3834:
-------------------------------
Summary: Unused Command.java fields NAME, DESCRIPTION and USAGE
Key: HDFS-3834
URL: https://issues.apache.org/jira/browse/HDFS-3834
Project: Hadoop HDFS
Issue Type: Improvement
Affects Versions: 3.0.0
Reporter: Jing Zhao
Assignee: Jing Zhao
Priority: Minor
The static fields NAME, USAGE AND DESCRIPTION in Command.java are not used and
cannot be overridden by subclasses since Java does not support static variable
overriding. We can get rid of these three fields in the Command.java and only
keep them as static fields in subclasses.
