Hi all,
I submit a flink job through yarn-cluster mode and cancel job with
savepoint option immediately after job status change to deployed. Sometimes i
met this error:
org.apache.flink.util.FlinkException: Could not cancel job xxxx.

I check the jobmanager log, no error found. Savepoint is correct saved in
hdfs. Yarn appliction status changed to FINISHED and FinalStatus change to
KILLED.
I think this issue occur because RestClusterClient cannot find jobmanager
addresss after Jobmanager(AM) has shutdown.
My flink version is 1.5.3.
Anyone could help me to resolve this issue, thanks!
devin.
