There is a topology of 3 operator, such as, source, parser, and persist.
Occasionally, 5 subtasks of the source encounters exception and turns to
failed, at the same time, one subtask of the parser runs into exception and
turns to failed too. The jobmaster gets a message of the parser's failed. The
jobmaster then try to cancel all the subtask, most of the subtasks of the three
operator turns to canceled except the 5 subtasks of the source, because the
state of the 5 ones is already FAILED before jobmaster try to cancel it. Then
the jobmaster can not reach a final state but keeps in Failing state meanwhile
the subtask of the source kees in canceling state.
The job run on a flink 1.7 cluster on yarn, and there is only one tm with 10
slots.
The attached files contains a jm log , tm log and the ui picture.
The exception timestamp is about 2019-06-16 13:42:28.
