Hi, vino:
Thanks for your answer. When I set 20 parallelism, I can run job succeed
every time. When setting 40 parallelism, sometimes I can submit it
successfully, sometimes throw the exception. When setting 60 parallelism at the
time, it has not been submitted successfully, always this exception.So I don't
think it has anything to do with my program.

Hi mailtolrl,
Can you share more context about your program and UDAF.
Best,
Vino

My flink streaming job use a udaf, set 60 parallelisms，submit job in yarn
cluster mode，and then happens every time I start.
