------------------------------------
One quick question, I noticed the following change to TestLazyPrimitive:
{noformat}
diff --git

which I am concerned about being backwards incompatible. [~chinnalalam]
actually added this years ago in HIVE-2465. Chinna, what are your thoughts on
this change?
> Use multiple-characters as field delimiter

> Key: HIVE-5871
> URL: https://issues.apache.org/jira/browse/HIVE-5871
> Project: Hive
> Issue Type: Improvement
> Components: Contrib
> Affects Versions: 0.12.0
> Reporter: Rui Li
> Assignee: Rui Li
> Attachments: HIVE-5871.2.patch, HIVE-5871.3.patch, HIVE-5871.4.patch,

>
> By default, hive only allows user to use single character as field delimiter.
> Although there's RegexSerDe to specify multiple-character delimiter, it can
> be daunting to use, especially for amateurs.
> In the patch, I add a new SerDe named MultiDelimitSerDe. With
> MultiDelimitSerDe, users can specify a multiple-character field delimiter
> when creating tables, in a way most similar to typical table creations.
