Sergey Dudoladov commented on FLINK-1400:
-----------------------------------------
It's a bit confusing since the Job Manager Web interface shows the "built-in"
Task Manager has a data port.
I would prefer to run several TMs locally so that I can test my changes to
Flink on my PC before trying them in a cluster.
> In local mode, the default TaskManager won't listen on the data port.

> Key: FLINK-1400
> URL: https://issues.apache.org/jira/browse/FLINK-1400
> Project: Flink
> Issue Type: Bug
> Affects Versions: 0.9
> Environment: Ubuntu 14.04 LTS
> Reporter: Sergey Dudoladov
> Priority: Minor
>
> The Task Manager automatically started by the Job Manager (JobManager.scala,
> appr. line 470) in the local mode does not listen on the dataport.
> To reproduce:
> 1) Start Flink via ./start-local.sh
> 2) Look up the data port number on locahost:8081 -> "Task Managers" tab
> 3) sudo netstat -taupen | grep "dataport_number "
>
> Or start the second Task Manager and run Flink with the degree of
> parallelism 2 (assuming one slot per Task Manager)
> 4) ./flink run -p 2 ...
> Task Managers started via ./taskmanager.sh work fine.
