> 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.
