> Turns out KMS delegation token renewal feature (HADOOP-13155) does not work well with client side impersonation.
> In a MR example, an end user (UGI:user) gets all kinds of DTs (with renewer=yarn), and pass them to Yarn. Yarn's resource manager (UGI:yarn) then renews these DTs as long as the MR jobs are running. But currently, the token is used at the kms server side to decide the renewer, in which case is always the token's owner. This ends up rejecting the renew request due to renewer mismatch.
