> As  YARN-9768 described:
> Delegation token renewer thread in RM (DelegationTokenRenewer.java) renews 
> HDFS tokens received to check for validity and expiration time.
> This call is made to an underlying HDFS NN or Router Node (which has exact 
> APIs as HDFS NN). If one of the nodes is bad and the renew call is stuck the 
> thread remains stuck indefinitely. The thread should ideally timeout the 
> renewToken and retry from the client's perspective.
> But it only consider the app recovery, not consider the app submitted:
> !image-2021-04-27-11-38-29-162.png|width=516,height=428!
> It will cause the app submitted not retry, when renew token (HDFS Namenode/ 
> Router) timeout.
