@Neeraj Sabharwal: Thanks a lot for your testing. I see you have tested it for a unix user(neeraj) who is part of a unix group(hdpadmin).Which is working fine for me. But my requirement is we have some users where they don't connect to server,they directly use some tools (like Aqua Data Studio or SQL client or Teradata client) and we validate them by login to our cluster by their LDAP(active directory) with jdbc string or though beeline. And when they submit their job then they have to set property mapred.job.queue.name and run their jobs. So my point is can we configure CS view for ldap or AD groups as well ? I tried it for groups but getting below error. But when I tried for user specific then it is working(as expected) g:adhdpadm:batch ERROR : Failed to execute tez graph. org.apache.tez.dag.api.TezException: org.apache.hadoop.yarn.exceptions.YarnException: Failed to submit application_1455533826426_0025 to YARN : Failed to submit application application_1455533826426_0025 submitted by user saurkuma reason: No groups found for user saurkuma u:saurkuma:batch: working ...
