zhijiang updated FLINK-13762:
-----------------------------
Description: It is only for simplifying the implementations of specific
methods to not wrap the exception into {{RuntimeException}}. (was: Currently
StreamOneInputProcessor and StreamTwoInputSelectableProcessor have separate
implementations of ForwardingValveOutputHandler. Especially for the
implementation in StreamTwoInputSelectableProcessor, it is involved in the
check logic for different input index which would be a blocker for the
following unification of StreamTaskInput/Output.
We could implement a unified ForwardingValveOutputHandler and extract the check
logic for different inputs into the upper StreamTwoInputSelectableProcessor
layer.
Note: StreamTwoInputProcessor would be removed finally, so we keep it as
current way.)
