> We observed in our production environment that the jobs submitted with a RM 
> delegation token were continually failing to start.
> Upon further investigation we figured out the following Stack Trace as the 
> culprit -
> {code}
> java.io.IOException: Failed to renew token: Kind: HDFS_DELEGATION_TOKEN, 
> Service: ha-hdfs:prod-EMPTY-hbase4a, Ident: (token for sfdc: 
> HDFS_DELEGATION_TOKEN 
> owner=hbase/hbase4a-dnds1-86-ia7.ops.sfdc....@hbase4a-ia7.app.sfdc.net, 
> renewer=sfdc, realUser=, issueDate=1744651400720, maxDate=1745256200720,

> We took a look at the code and figured out that as part of the 
> handleAppSubmitEvent we do catch the IOException and do request a

> DelegationTokenRenewerAppRecoverEvent
> Code Pointer -

>                   evt.shouldCancelAtEnd());
>               continue;
>             }{code}
> The idea is to add a or statement in the event check.
> evt instanceof DelegationTokenRenewerAppRecoverEvent || evt instanceof
