@subhash parise Thanks for you answer but docs you pointing me are for HDP technical preview which required download of 10GB vm. And another one is to create a build that is difficult to integrate.

Please help me if you have any other source or links...

Try this, this is from Gopal on Apache Hive mailing list

"Though if you're interested in measuring performance, I debate the

usefulness of an in-memory buffer-cache for a 1-node & cpu/memory constrained VM.

> Is it a complicated work to build it with Do It Yourself so to speak?Complicated enough that I have automated it (at least for myself & most of the devs). https://github.com/t3rmin4t0r/tez-autobuild/blob/llap/README.md That setup should work as long as you have a base Apache compatible hadoop-2.7.1 install. Because the way to deploy LLAP is a "yarn jar" & then have YARN run the instances, no part of the actual deploy requires root on any worker node. All you need is access to the metastore db (new features in the metastore) and a single Zk ensemble to register LLAP onto. That makes it really easy to "drop into" an existing YARN cluster where you're not an admin, but the LLAP install is then tied to a single user (you). That's set up a bit unconventionally since LLAP was never meant to hijack a user like this and allow access from the CLI. The real reason for that is so that I can do hive --debug and debug the CLI from remote much more easily than HiveServer2's massive number of threads. I did put up a demo GIF earlier during the Summit, which should give you an idea of how fast/slow LLAP is with S3 data (which is when the read-through cache really comes into the limelight). <https://twitter.com/t3rmin4t0r/status/748630764959338497/photo/1>"
