             Summary: Main.java shouldn't have hard-coded lists of commands for usage
                 Key: ACCUMULO-4605
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-4605
             Project: Accumulo
          Issue Type: Bug
            Reporter: Christopher Tubbs
             Fix For: 2.0.0


ACCUMULO-4490 added hard-coded lists of commands in the Main class, for the purposes of usage. However, this regresses what ACCUMULO-3514 was trying to fix.

In addition, the current implementation results in NullPointerExceptions when one of the hard-coded keywords are not found in the classloader.

Main should be fixed so that it does not depend on hard-coded lists of KeywordExecutables.

[~mikewalch] mentioned to me that part of the reason this was done was to affix the ordering of the usage. I think that goal can be achieved by extending the KeywordExecutable interface to include a grouping or ordering attribute instead.
