Yang Wang commented on FLINK-15297:
-----------------------------------
[~tison] I'm not sure how this could happen? Does the flink application on Yarn
finished very quickly that when `YarnClusterDescriptor` first get the
application report, the state is "FINISHED". Also i think it could not happen
in 250ms that application state changes from "ACCEPTED" to "FINISHED".
> Do not throw exception if YARN Application switched to FINISHED immediately
> after deployed in YarnClusterDescriptor#startAppMaster

> Currently we throw an exception in {{YarnClusterDescriptor#startAppMaster}}
> if we first detect {{FINISHED}} before {{RUNNING}}. However, it is possible a
> legal state that the application finished normally immediately.
> Right now we always try to connect the Dispatcher so it may be fine to throw
> the exception a bit earlier(otherwise when connect to a closed cluster an
> exception thrown also), but it is semantically wrong. Internally we have a
> code path that only required to report the ApplicationReport and it causes
> trouble.
