> Further inspection shows the KMS IP is from another cluster. The RM is before HADOOP-14445,
so needs to read from config. The config rightfully doesn't have the other cluster's KMS configured.
> Although HADOOP-14445 will make this a non-issue by creating the provider from token
service, we should fix 2 things here:
> - KMS token renewer should throw instead of return 0. Returning 0 when not able to renew
shall be considered a bug in the renewer.
> - Yarn RM's {{DelegationTokenRenewer}} service should validate the return and not go
into this busy loop.
