[jira] [Commented] (KAFKA-1680) JmxTool exits if no arguments are given

["Jonathan Rafalski (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/KAFKA-1680?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14329407#comment-14329407 ] 

Jonathan Rafalski commented on KAFKA-1680:
------------------------------------------

is this still a valid bug?  Seems to me that if they don't provide a jmx-url the tools will not work as it defaults to a nonworking generic service address. 

I have only been working on this tool for Kafka-1679 but I feel like we should require the jmx-url so if no args are passed it is correct that we should dump the help and exit.

> JmxTool has no required arguments, but it exits if no arguments are provided. 
> You can work around this by passing a non-option argument, which will be ignored, e.g.{{./bin/kafka-run-class.sh kafka.tools.JmxTool xxx}}.
> It looks like this was broken in KAFKA-1291 / 6b0ae4bba0d0f8e4c8da19de65a8f03f162bec39
