--------------------------------------
Are you talking about running watch dog daemon process to monitor the
TaskManager process?
> TaskManager shell scripts restart JVMs on process failures

> Key: FLINK-1812
> URL: https://issues.apache.org/jira/browse/FLINK-1812
> Project: Flink
> Issue Type: Improvement
> Components: Start-Stop Scripts
> Affects Versions: 0.9
> Reporter: Stephan Ewen
>
> Currently, the TaskManager processes may die under certain fatal exceptions
> that prevent the TaskManager to proceed.
> Most of those problems can be fixed by a clean process (JVM) restart.
> We can make the system more resilient by changing the {{taskmanager.sh}} bash
> script to restart the processes upon a certain exit code.
> The TaskManager returns that exit code whenever it kills itself due to a
> problem that requires a clean JVM.
