Shawn Weeks commented on HIVE-20020:
------------------------------------
MultiDelimitSerDe has been in contrib for several years now, what is needed to
actually make it a proper SerDe so we can just eliminate the issue altogether?
I know it still has a rather nasty bug in it and I've gone to using the Hive
split() function instead but I don't think it's that much work to fix that.
> 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.
