Description

The flame graph cannot be generated forever when multiple tasks in the same TM. It's caused by FLINK-26074

 

Root cause:

A Set cannot be converted to an ImmutableSet during the aggregation of ExecutionAttemptIDs. It will cause only the first ExecutionAttemptID of the TM to be added to the set, the second ExecutionAttemptID will fail.
