Thank you. Forgot to mention that the error occurred when I was testing my
code in Intellij.

Hi Shuang,
Normally
Hi Shuang,
Normally this exception you mentioned is not the root cause of failover, and it
is mainly caused by cancel process to make task exit.
You can further check whether there are other failures in job master log to
find the root cause.
Best,
Zhijiang
