Shilun Fan commented on YARN-9708: ---------------------------------- [~krishan1390] Thank you very much for your question. I will add a document as soon as possible to explain this feature. When completing this pr, we refer to the design of Router of HDFS RBF and RMDelegationTokenManager. I will complete the document in 1-2 days. > Yarn Router Support DelegationToken > ----------------------------------- > > Key: YARN-9708 > URL: https://issues.apache.org/jira/browse/YARN-9708 > Project: Hadoop YARN > Issue Type: New Feature > Components: router > Affects Versions: 3.4.0 > Reporter: Xie YiFan > Assignee: Shilun Fan > Priority: Major > Labels: pull-request-available > Attachments: Add_getDelegationToken_and_SecureLogin_in_router.patch, > RMDelegationTokenSecretManager_storeNewMasterKey.svg, > RouterDelegationTokenSecretManager_storeNewMasterKey.svg > > > 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. > -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
