The incompatibilities were not avoidable in a set of situations - a lot of
those
I'm using Hive 3.1 on Tez/LLAP and I must say the experience was not good
but it was worth it. We built Hive from HDP's hive-release and add Tez UI
back, combined that with Hue 4.3 (also built from Cloudera Hue). Now that
the two companies have merged I think things are going to get better (I'm
I have changes jobs 3 times since tez was introduced. It is a true waste of
compute resources and time that it was never patched in. So I either have
to waste my time patching it in, waste my time running a side deployment,
or not installing it and waste money having queries run longer on mr/spark
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.

Hi,

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
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.

Following blog summarizes part of the work (bit old, we currently run Tez
0.9.1 on CDH 5.16.1).

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:
