> Last year, I reported the similar bug of TemporalJoin cause state leak.
> Detail: FLINK-21833
> Recently, I found the fix code can reduce the the leak size but can not
> resolve it completely.
> The code of line 213 cause it and the right fix is to invoke cleanUp() method.
> In FLINK-21833, we discussed when the code is running on line 213, that means
> Left State, Right State, registeredTimerState is empty, actually the Left
> State and Right State value(MapState) is empty but the key is still be in
> state, So invoke state.clear() is necessary.
