Stephan Ewen commented on FLINK-6487:
-------------------------------------
The mini cluster is also used behind the Local[Stream]ExecutionEnvironment, so
for examples, testing, debugging, etc.
It is definitely meant to be used by users, not just by tests.
> Remove JobManager local mode

> Key: FLINK-6487

> Project: Flink
> Issue Type: Bug
> Components: Runtime / Coordination
> Reporter: Stephan Ewen
> Priority: Major
>
> We should remove the "local" mode from the JobManager.
> Currently, the JobManager has the strange "local" mode where it also starts
> an embedded Task Manager.
> I think that mode has caused confusion / problems:
> - No TaskManagers can join the cluster
> - TaskManagers do not support querable state
> - It is redundant code to maintain
> At the same time, the mode does not help at all:
> - The MiniCluster does not use that mode
> - Starting from scripts, the {{start-cluster.sh}} works out of the box,
> creating a proper local cluster, but in two processes, rather than one.
