-----------------------------------
Summary: 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
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.
