Should we use the cmd type of UpdateRenewDelegationTokenRequest

This is being done intentionally so that we don't need new class or some special handling in OMRatisUtils createOMClientRequest().

Same is explained in the code comments.

An UpdateRenewDelegationTokenRequest body with RenewDelegationTokenRequest type in OMRequest is a bit hacky. But I'm OK with it if otherwise takes too much changes.

Ya can understand that. Otherwise, we need some changes in createClientRequest in ratis to act upon UpdateRenewDelegationTokenRequest or RenewDelegationTokenRequest to return OMGetDelegationTokenRequest object or have separate new classes for both of them. And for one only preExecute will be needed, for other validateAndUpdateCache only will be needed. So, I will leave this as it is.

I agree this is a bit hard to follow. I also had a long discussion with Bharat while reviewing the createDelegationToken patch. I am okay to live with for now to avoid creating yet another request class.
