Matthias Pohl commented on FLINK-29576:
---------------------------------------
Adding additional log output reveals that the Operator ID in question, indeed,
is not registered with the {{DefaultOperatorCoordinatorHandler}}:
Those are the IDs registered in a run:
{code}

...that fails with not finding the {{OperatorHandler}} for a completely
different ID {{feca28aff5a3958840bee985ee7de4d3}}:
