Rohith commented on YARN-3646: ------------------------------ Thanks for working on this issue.. The patch overall looks good to me. nit : Can the test moved to Yarn package since issue is in Yarn? Otherwise if there is any changed in the RMProxy, test will not run. > Applications are getting stuck some times in case of retry policy forever > ------------------------------------------------------------------------- > > Key: YARN-3646 > URL: https://issues.apache.org/jira/browse/YARN-3646 > Project: Hadoop YARN > Issue Type: Bug > Components: client > Reporter: Raju Bairishetti > Attachments: YARN-3646.patch > > > 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.
