---------------------------------
Resolution: Duplicate
> KMSClientProvider#addDelegationTokens should use ActualUgi for proxy user

> Key: HADOOP-11773
> URL: https://issues.apache.org/jira/browse/HADOOP-11773
> Project: Hadoop Common
> Issue Type: Bug
> Reporter: Xiaoyu Yao
> Assignee: Xiaoyu Yao
> Priority: Blocker
>
> In a secure cluster with kerberos, when the
> KMSClientProvider#addDelegationTokens is called in the context of a proxied
> user, the SPNEGO authentication is currently made with the currentUser (the
> proxied user) as the Principal, which does not have a kerberos ticket and
> fail as shown below. This should be done in the context of the real user
> represented by actualUgi introduced in HADOOP-11176.
> The following stack was found from Hiveserver2 queries in a secure cluster. I
> will post a patch for this shortly.
