Spongebob updated FLINK-32739:
------------------------------
Description:
In my flink standalone cluster, I config 2 taskmanagers. Then I test with
following steps:
# submit streaming job which was configed to fixed restart strategy to flink
session environment
# this job was running on taskmanager1. Then I killed the taskmanager1.
# this job turned to be failed after restarting attemps.
this job could not be transported to taskmanager2 which had enough slots as
expected.
