> 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.
