[jira] [Updated] (TEZ-1640) Unable to achieve Secured Impersonation

     [ https://issues.apache.org/jira/browse/TEZ-1640?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Subroto Sanyal updated TEZ-1640:
--------------------------------
    Description: 
My client is running with user "subroto" and following are the entries in the xmls:
{code:xml|title=core-site.xml|borderStyle=solid}
               <property>
                <name>hadoop.proxyuser.subroto.groups</name>
                <value>impersonatedgroup</value>
                </property>

               <property>
                <name>hadoop.proxyuser.subroto.hosts</name>
                <value>*</value>
               </property>
{code}

I have a user _qa_ which belongs to the the group _impersonatedgroup_ .
Following is the code to launch the DAGAppMaster
{code:java|title=TezClientWrapper.java|borderStyle=solid}
TezClient tezClient = SecureGridMode.executePossiblyImpersonated(conf, new PrivilegedExceptionAction<TezClient>() {
                @Override
                public TezClient run() throws Exception {
                    final TezConfiguration tezConf = createTezConf(conf, jobContext);
                    if (amSpecificProperties != null) {
                        applyAmSpecificProperties(tezConf, amSpecificProperties);
                    }

                    UserGroupInformation currentUser = UserGroupInformation.getCurrentUser();
                    LOG.info("Current User:" + currentUser);
                    File tokenFile = new File(System.getProperty("java.io.tmpdir"), tezSessionName.replaceAll("[^a-zA-Z0-9]", ""));
                    LOG.info("Token File:" + tokenFile.getAbsolutePath());
                    currentUser.getCredentials().writeTokenStorageFile(UriUtil.toPath(tokenFile.getAbsoluteFile()), conf);
                    tezConf.set(TezConfiguration.TEZ_CREDENTIALS_PATH, tokenFile.getAbsolutePath());
                    TezClient tezClient = TezClient.create(tezSessionName, tezConf, createSession, localResourceMap, currentUser.getCredentials());
                    tezClient.setAppMasterCredentials(currentUser.getCredentials());
                    tezClient.start();
                    tezClient.waitTillReady();
                    return tezClient;
                }
            });{code}

The logs so obtained from this piece of code execution is:
{noformat}Current User:qa (auth:PROXY) via subroto@EC2.INTERNAL (auth:KERBEROS){noformat}

The  code piece fails in: _tezClient.waitTillReady();_
>From the Resource Manager UI I can see that a application is launched with user _qa_.
