Exactly. The wrapping shell script would restart the TaskManager if the exit
code was the specific exit code.
Seems rather straightforward, or am I overlooking something?

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.

Are you talking about running watch dog daemon process to monitor the
TaskManager process?
