Guowei Ma commented on FLINK-23235:
-----------------------------------
Investigated the reason for this problem: At present, an operator may still
complete the checkpoint after receiving "EndOfInput". Leading to GlobalCommit
will submit an "end of input".Specifically, when Checkpoint4 is successful, the
source node has sent the end-of-input message
!screenshot-1.png!
Because at present, it is not certain that an operator can complete a
checkpoint after receiving "EndOfInput". Therefore, in Streaming mode, I will
tell the test sink not to output the string "end of input" in endOfInput.
In the future, this will be restored when Final-CP becomes a certainty.
