>             Project: Hadoop Common
>          Issue Type: Improvement
>            Reporter: Yongjun Zhang

> We run into quite some customer cases about authentication failures related to KMS delegation
token. It would be nice to see a log for each stage of the token:
> 1. creation
> 2. renewal
> 3. removal upon cancel
> 4. remove upon expiration
> So that when we correlate the logs for the same DT, we can have a good picture about
what's going on, and what could have caused the authentication failure.
> The same is applicable to other delegation tokens.
> NOTE: When log info about delagation token, we don't want leak user's secret info.
