Reg " hive concurrency not working" in HDP. yes, it's known issue in HDP and with Hue 2.6
I have below information on this issue and hope it will help you. -------------------------------- When you are running Hive queries through Hue (Beeswax), users are unable to run multiple queries concurrently. In practice, this doesn't matter if it is separate browser sessions, separate clients, etc. it seems to be tied to the user. In looking at the way Tez works and looking through the code for the patch in Hive 0.14 that supports concurrent queries in general with Tez, it does not support parallel queries in a particular TezSession, only serial queries. This is also documented in Tez documentation. It seems the way that Hive creates a session is based upon the user. Upon further digging, we found a ticket HIVE-9223 that is in open state which describes this issue. ----------------------------------- Regards, Divakar On Wed, Aug 3, 2016 at 11:50 AM, Sergey Shelukhin <ser...@hortonworks.com> wrote: > Can you elaborate on not working?
