Subject [jira] [Updated] (CASSANDRA-6824) fix help text for stress counterwrite
Date Fri, 07 Mar 2014 23:09:46 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-6824?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Benedict updated CASSANDRA-6824:
--------------------------------

    Attachment: 6824-2.txt

Actually it looks like this was a minor bug - it should accept both commands. Had a quick
look and this was only functioning for printing of help, not for running the commands, which
was a bit of a mistake. 

Attached a patch that fixes this, and also adds a line stating "help <command>" right
at the top, as I had a number of queries from people about how on earth it worked that were
mostly solved by giving them that command; it's not obvious from its position in the normal
print out that it would be so useful.
