How to run multiple DAG concurrently in one Tez AM in Hive

New Contributor

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.

There is no way to run multiple DAG concurrently in single Tez AM, and this is Tez limitation. But HiveServer2 support multiple concurrent queries with multiple Tez AM.
