[jira] [Created] (FLINK-1796) Local mode TaskManager should have a process reaper

Stephan Ewen created FLINK-1796:
-----------------------------------

             Summary: Local mode TaskManager should have a process reaper
                 Key: FLINK-1796
                 URL: https://issues.apache.org/jira/browse/FLINK-1796
             Project: Flink
          Issue Type: Bug
          Components: JobManager
    Affects Versions: 0.9
            Reporter: Stephan Ewen
            Assignee: Stephan Ewen
             Fix For: 0.9


We use process reaper actors (a typical Akka design pattern) to shut down the JVM processes when the core actors die, as this is currently unrecoverable.

The local mode uses the process reaper only for the JobManager actor, not for the TaskManager actor. This may lead to dead stale JVMs on critical TaskManager errors and makes debugging harder.
