----------------------------------------
Summary: TaskManagers should log their `ResourceID` during startup
Key: FLINK-10223
URL: https://issues.apache.org/jira/browse/FLINK-10223
Project: Flink
Issue Type: Improvement
Components: Distributed Coordination
Affects Versions: 1.5.3, 1.6.1
Reporter: Konstantin Knauf
To debug exceptions like "org.apache.flink.util.FlinkException: The assigned
slot <SlotId> was removed." in the master container it is often helpful to
know, which slot was provided by which Taskmanager. The only way to relate
slots to TaskManagers right now, seems to be to enable DEBUG logging for
`org.apache.flink.runtime.jobmaster.slotpool.SlotPool`.
This would be solved, if each Taskmanager would log out their `ResouceID`
during startup as the `SlotID` mainly consists of the `ResourceID` of the
providing Taskmanager. For Mesos and YARN the `ResourceID` has an intrinsic
meaning, but for a stand-alone or containerized setup the `ResourceID` is just
the a random ID.
