-------------------------------

             Summary: Add Yarnclient#getDelegationToken API implementation and SecureLogin in router
                 Key: YARN-9708
                 URL: https://issues.apache.org/jira/browse/YARN-9708
             Project: Hadoop YARN
          Issue Type: New Feature
          Components: router
    Affects Versions: 3.1.1
            Reporter: Xie YiFan
         Attachments: Add_getDelegationToken_and_SecureLogin_in_router.patch

1.we use router as proxy to manage multiple cluster which be independent of each other in order to apply unified client. Thus, we implement our customized AMRMProxyPolicy that doesn't broadcast ResourceRequest to other cluster.

2.Our production environment need kerberos. But router doesn't support SecureLogin for now.
https://issues.apache.org/jira/browse/YARN-6539 desn't work. So we improvement it.

3.Some framework like oozie would get Token via yarnclient#getDelegationToken which router doesn't support. Our solution is that adding homeCluster to ApplicationSubmissionContextProto & GetDelegationTokenRequestProto. Job would be submitted with specified clusterid so that router knows which cluster to submit this job. Router would get Token from one RM according to specified clusterid when client call getDelegation meanwhile apply some mechanism to save this token in memory.
