> 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.
