Shawn Weeks commented on HIVE-20020:
------------------------------------
Yeah, and really what I was trying to say is that aside from the
MultiDelimiterSerde, just about everything else in there is just examples. If
we could get out of there what's actually being used we could quit include
hive-contrib altogether. I don't really see how compiled copies of the examples
actually belongs in the standard installation.
> Hive contrib jar should not be in lib

> Key: HIVE-20020
> URL: https://issues.apache.org/jira/browse/HIVE-20020
> Project: Hive
> Issue Type: Improvement
> Components: Contrib
> Reporter: Johndee Burks
> Priority: Trivial
>
> Currently the way hive is packaged it includes hive-contrib-<version>.jar in
> lib, we should not include it here because it is picked up by services like
> HS2. This creates a situation in which experimental features such as the
> [MultiDelimitSerDe|https://github.com/apache/hive/blob/master/contrib/src/java/org/apache/hadoop/hive/contrib/serde2/MultiDelimitSerDe.java]
> are accessible without understanding how to really install and use it. For
> example you can create a table using HS2 via beeline with the aforementioned
> SerDe and it will work as long you do not do M/R jobs. The M/R jobs do not
> work because the SerDe is not in aux to get shipped into distcache. I propose
> we do not package it this way and if someone would like to leverage an
> experimental feature they can add it manually to their environment.
