Hi,
We are using CDH 5, with Impala 2.7.0-cdh5.9.1 and Hive 1.1 (MapReduce)
I can't find the info regarding Hive on Tez performance compared to Impala.
Does someone know or compared it?
Thanks
Artur Sukhenko
Out of band question. Given:

Does cdh finally ship with a tea you dont have to manually patch in?

I tested the performance of Impala 2.12.0+cdh5.15.2+0 in Cloudera CDH
5.15.2 a while ago. I compared it with Hive 3.1.1 on MR3 (where MR3 is a
new execution engine for Hadoop and Kubernetes). You can find the result at:

No, not yet. However, we have built Tez on CDH and it runs just fine.
Following blog summarizes part of the work (bit old, we currently run Tez
0.9.1 on CDH 5.16.1).

Blog says use ATS from open source hadoop, which will not work if
Thanks Sungwoo, very nice articles.

Lol. I was hoping that the merger would unblock the "saltyness". I wonder
what is the official position is now because back in the day there was a
puff piece produced to the effect of hive was not the way forward and
impala is the bees knees.

Down that path you'll also need to deploy a slightly newer version of Hive as
well, because Hive 1.1 is a bit ancient & has known bugs with the tez planner
code.
You effectively end up building the hortonworks/hive-release
If we install our own build of Hive, we'll be out of support from CDH.
Tez is not supported anyway and we're not touching any CDH bits, so it's not a
big issue to have our own build of Tez engine.
