Zhu Zhu commented on FLINK-28878:
---------------------------------
Thanks for reporting it! [~hxbks2ks]
The test fails due to an unexpected slowness of test running (may be due to an
environment slowness). The slowness resulted in a slow request timeout and
triggered a failover. This made the job failover number to be 2 instead of the
expected 1.
Will increase the slot request timeout to make the tests more stable.
