CR Hota commented on HDFS-13972: -------------------------------- [~elgoiri] Thanks for the comment. In terms of testing just this feature, since its not an input/output param, the only way I tried locally is by refactoring and adding a simple check for method name. But to prevent erroneous usage of this by developers for other methods may be tricky. Is there anything specific you have in mind? {code:java} private void setSuperUser(String method) throws IOException { if ("getDatanodeReport".equals(method)) { UserGroupInformation loginUser = UserGroupInformation.getLoginUser(); RouterRpcServer.setCurrentUser(loginUser); } } private DatanodeInfo chooseDatanode(final Router router, final String path, final HttpOpParam.Op op, final long openOffset, final String excludeDatanodes) throws IOException { // We need to get the DNs as a privileged user final RouterRpcServer rpcServer = getRPCServer(router); setSuperUser("getDatanodeReport"); DatanodeInfo[] dns = null; try { dns = rpcServer.getDatanodeReport(DatanodeReportType.LIVE); } catch (IOException e) { LOG.error("Cannot get the datanodes from the RPC server", e); } finally { // Reset ugi to remote user for remaining operations. RouterRpcServer.resetCurrentUser(); } {code} > RBF: Support for Delegation Token (WebHDFS) > ------------------------------------------- > > Key: HDFS-13972 > URL: https://issues.apache.org/jira/browse/HDFS-13972 > Project: Hadoop HDFS > Issue Type: Sub-task > Reporter: Íñigo Goiri > Assignee: CR Hota > Priority: Major > Attachments: HDFS-13972-HDFS-13891.001.patch, > HDFS-13972-HDFS-13891.002.patch, HDFS-13972-HDFS-13891.003.patch, > HDFS-13972-HDFS-13891.004.patch, HDFS-13972-HDFS-13891.005.patch, > HDFS-13972-HDFS-13891.006.patch, HDFS-13972-HDFS-13891.007.patch, > HDFS-13972-HDFS-13891.008.patch, HDFS-13972-HDFS-13891.009.patch, > HDFS-13972-HDFS-13891.010.patch, HDFS-13972-HDFS-13891.011.patch, > HDFS-13972-HDFS-13891.012.patch, HDFS-13972-HDFS-13891.013.patch, > TestRouterWebHDFSContractTokens.java > > > HDFS Router should support issuing HDFS delegation tokens through WebHDFS. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
