             Summary: Implement TokenRenewer in KMS and HttpFS
                 Key: HADOOP-13155
                 URL: https://issues.apache.org/jira/browse/HADOOP-13155
             Project: Hadoop Common
          Issue Type: Bug
            Reporter: Xiao Chen
            Assignee: Xiao Chen


DelegationToken is done in Yarn by {{DelegationTokenRenewer}}, where it calls {{Token#renew}} and uses ServiceLoader to get the renewer class ([code|https://github.com/apache/hadoop/blob/trunk/hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/security/token/Token.java#L382])

We seem to miss the token renewer class in KMS/HttpFSFileSystem, and hence Yarn defaults to {{TrivialRenewer}} for DT of these kinds, resulting in the token not renewed.

As a side note, {{HttpFSFileSystem}} does have a {{renewDelegationToken}} API, but I don't see it invoked in hadoop code base. KMS does not have any renew hook.
