Hello, I am a graduate student, and using Hive for my research. I have a question about Hive + Tez. Currently, I am using beeline to submit query to hiveserver2. I know it will create a new App Master for one beeline connection, and submit one DAG / one query sequentially. Now I want to run multiple DAG concurrently in one Tez App Master. How can I do it? I also take a look at this https://issues.apache.org/jira/browse/HIVE-11402 But still cannot figure out how to do it. Thank you guys.

This is what I get from log at DEBUG Level: http://imgur.com/hBw4yZg So the reason is that our token is expired, but I don't know how to renew it. At I notice, in Tez source code, they also use TimelineClient to put entities to Yarn Timeline Server, they do not have anything to renew the token, right?

Hi, My team create an yarn application which can put entities to Yarn Timeline Server periodically. After we enable security with Kerberos on our cluster, our program still works fine. But when we change the yarn-site.xml as follows: http://imgur.com/EuY6EHs Our program cannot finish because of the Yarn Exceptions: http://imgur.com/s8uvNME So, what should we do to fix it?
