RE: Working Formula for Hive 0.13?
I have preliminary patch against spark1.0.2, which is attached to spark-2706. Now I am working on supporting both hive-0.12 and hive-0.13.1 with non-intrusive way (not breaking any existing hive-0.12 when introduce supporting new version). I will attach a proposal to solve multi-version support issue to spark-2706 soon. Thanks.

Re: Working Formula for Hive 0.13?
Thanks for working on this! Its unclear at the moment exactly how we are going to handle this, since the end goal is to be compatible with as many versions of Hive as possible. That said, I think it would be great to open a PR in this case. Even if we don't merge it, thats a good way to get it on people's radar and have a discussion about the changes that are required.

RE: Working Formula for Hive 0.13?
From my perspective, there're few benefits regarding Hive 0.13.1+. The following are the 4 major ones that I can see why people are asking to upgrade to Hive 0.13.1 recently. 1. Performance and bug fix, patches. (Usual case) 2. Native support for Parquet format, no need to provide custom JARs and SerDe like Hive 0.12. (Depends, driven by data format and queries) 3. Support of Tez engine which gives performance improvement in several use cases (Performance improvement) 4. Security enhancement in Hive 0.13.1 has improved a lot (Security concerns, ACLs, etc) These are the major benefits I see to upgrade to Hive 0.13.1+ from Hive 0.12.0. There may be others out there that I'm not aware of, but I do see it coming. my 2 cents. From: mich...@databricks.com Date: Mon, 25 Aug 2014 13:08:42 -0700 Subject: Re: Working Formula for Hive 0.13?

Re: Working Formula for Hive 0.13?
Yes, it is published. As of previous versions, at least, hive-exec included all of its dependencies *in its artifact*, making it unusable as-is because it contained copies of dependencies that clash with versions present in other artifacts, and can't be managed with Maven mechanisms. I am not sure why hive-exec was not published normally, with just its own classes. That's why it was copied, into an artifact with just hive-exec code. You could do the same thing for hive-exec 0.13.1. Or maybe someone knows that it's published more 'normally' now. I don't think hive-metastore is related to this question?

Yeah so we need a model for this (Mark - do you have any ideas?). I did this in a personal github repo. I just did it quickly because dependency issues were blocking the 1.0 release: https://github.com/pwendell/hive/tree/branch-0.12-shaded-protobuf I think what we want is to have a semi official github repo with an index to each of the shaded dependencies and what version is included in which branch. - Patrick On Mon, Jul 28, 2014 at 10:02 AM, Mark Hamstra m...@clearstorydata.com wrote: Where and how is that fork being maintained?

Re: Working Formula for Hive 0.13?
I've heard from Cloudera that there were hive internal changes between 0.12 and 0.13 that required code re-writing. Over time it might be possible for us to integrate with hive using API's that are more stable (this is the domain of Michael/Cheng/Yin more than me!). It would be interesting to see what the Hulu folks did. - Patrick On Mon, Jul 28, 2014 at 10:16 AM, Cheng Lian lian.cs@gmail.com wrote: AFAIK, according a recent talk, Hulu team in China has built Spark SQL against Hive 0.13 (or 0.13.1?) successfully.

I am not sure why hive-exec was not published normally, with just its own classes. That's why it was copied, into an artifact with just hive-exec code. You could do the same thing for hive-exec 0.13.1. Or maybe someone knows that it's published more 'normally' now. I don't think hive-metastore is related to this question?
