*How to reproduce*
Comment out the delay of 10s after the 1st TM is restarted to provoke the issue:
{code:bash}
echo "Restarting 1 TM"
$FLINK_DIR/bin/taskmanager.sh start
wait_for_number_of_running_tms 4
#sleep 10
echo "Killing 2 TMs"
kill_random_taskmanager
kill_random_taskmanager
wait_for_number_of_running_tms 2
{code}
Command to run the test:
{noformat}
FLINK_DIR=build-target/ flink-end-to-end-tests/run-single-test.sh skip flink-end-to-end-tests/test-scripts/test_streaming_bucketing.sh
