> We have set *yarn.resourcemanager.connect.wait-ms* to -1 to use FOREVER
> retry policy.
> Yarn client is infinitely retrying in case of exceptions from the RM as it is
> using retrying policy as FOREVER. The problem is it is retrying for all kinds
> of exceptions (like ApplicationNotFoundException), even though it is not a
> connection failure. Due to this my application is not progressing further.
> *Yarn client should not retry infinitely in case of non connection failures.*
> We have written a simple yarn-client which is trying to get an application
> report for an invalid or older appId. ResourceManager is throwing an
> ApplicationNotFoundException as this is an invalid or older appId. But
> because of retry policy FOREVER, client is keep on retrying for getting the
> application report and ResourceManager is throwing
> ApplicationNotFoundException continuously.
