TisonKun commented on FLINK-10558:
----------------------------------

[~till.rohrmann] I'd like to know if the present status excepted. As [~yanghua] 
commented on GitHub.

bq. @tillrohrmann For test case testTaskManagerFailure, the current test mode 
(based on stdout and stderr's special print message) cannot verify the Flip-6 
scene. Because it doesn't pre-start a TM, so I can only commit a job to drive 
the TM registration, but this will cause the Job's output to flush out the 
flink's output, which shares stdout and stderr. Therefore, many judgments will 
not take effect.

I wonder if on FLIP-6 yarn session mode, we'd like to (really) pre-start TMs, 
if so, we have to mark that the workaround(submit a job to drive th TM 
registration) is temporary.
