Thanks, @Neeraj Sabharwal . I think this prewarm is a little different from the issue I found, which I think is Tez session (AM) initialization and queue config issue. Are they related or depending on?

I followed all the instructions above. But it doesn't work. Issues I found: 1) After change the session config, Ambari won't restart HS2. It only restarts metastore and webhcat. I had to restart HS2 separately. 2) "Session per queue" config doesn't work. I changed it to 4, and tell Hive to initialize it, but after HS2 restart, it can only start 1 Tez session since the old 1 session per queue config seems to be still effective. 3) Initialized Tez session won't be used. Submitting query from beeline would try to start a new Tez session in the queue but it gets pended again.

I have set up my HiveServer2 to use 'hive1,hive2' as its default queues. I expect query submitted by the beeline tool would be running in those two queues, but I observed it runs in the 'default' queue. I also configured sessions per queue on HS2 to 2, but it seems it does not take effect. I am using Hive on Tez on HDP 2.3.2 and Ambari 2.1.2.1. Is there any other configurations required to make the Hive default queues and sessions per queue configs work?

Does HDP support running on RHEL 7.2? On Hortonworks documentation site, RHEL 7.x is documented as supported OS. Does the new released (Nov. 19) RHEL 7.2 included?

2.3.0 is not there. It would be great to keep older maintenance versions for each release. Users may want to develop applications against the same version on the Sandbox of their production cluster.

Where can I find the HDP Sandbox archive for development purpose? Current the latest HDP 2.3.2 sandbox is available on hortonworks.com. There is also an archive link on the page, I cannot find the maintenance release version I need (HDP2.3.0.0-2557).

Is the executeSQL processor able to leverage streaming capability of a JDBC driver level 4 or 5. This is quite important for us as if not it would mean that Nifi is not able
to get data in small batches that are processed progressively and that it needs to receive the whole dataset before going to processing.
e.g: if we are extracting 1 Million records we need to wait for the whole dataset to arrive to do any processing instead of receiving small batch of 10 records or 100 records that we process and
stream to the final location.
