> Change swstatus to give a simple "up" or "down" answer, instead of the
> current, confusing display
> -------------------------------------------------------------------------------------------------
>
> Key: TRAFODION-1609
> URL: https://issues.apache.org/jira/browse/TRAFODION-1609
> Project: Apache Trafodion
> Issue Type: Improvement
> Components: sql-general
> Reporter: Hans Zeller
> Assignee: Eason Zhang
> Priority: Minor
>
> The "swstatus" script used in cases where we did install_local_hadoop counts
> the MySQL processes and then simply invokes jps.
> It would be better if the script would check specifically for HMaster,
> NameNode, DataNode and maybe others, like NodeManager and ResourceManager. If
> any are missing, it should print out which ones are missing, otherwise it
> should just say something like "processes are up".
> It should also return an exit code of 0 if everything is up and 1 if some
> processes are missing.
