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 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.
