Timothy Chen updated MESOS-2261:
--------------------------------
Labels: newbie (was: )
> Better error message when both MESOS_MASTER and --master are set
> ----------------------------------------------------------------
>
> Key: MESOS-2261
> URL: https://issues.apache.org/jira/browse/MESOS-2261
> Project: Mesos
> Issue Type: Improvement
> Affects Versions: 0.21.0
> Reporter: Kevin Matzen
> Priority: Minor
> Labels: newbie
>
> I had MESOS_MASTER defined in a script and used it to launch mesos-slave.
> e.g. mesos-slave --master=$MESOS_MASTER
> I had not read the documentation stating MESOS_MASTER is already used for
> this purpose.
> http://mesosphere.com/docs/reference/mesos-slave/
> The error message mesos-slave prints is:
> Duplicate flag 'master' on command line
> This is a very unhelpful error message if you don't know about MESOS_MASTER.
