> In current documentation yarn.application-attempts: 10 is documented as resulting in
at most 10 application restarts. That is a bit misleading: YARN can perform up to 9 restarts
for "failed" attempts, resulting in 10 attempts. It can perform additional restarts for YARN
attempts that failed because of YARN operations: Node failures, preemption, NodeManager resyncs,
