Yo guys I noticed UDTFType ads a "distinctlike".

I am trying to document it for programming hive. This was added by hive-1003

http://svn.apache.org/viewvc/hive/trunk/ql/src/java/org/apache/hadoop/hive/ql/udf/UDFType.java?view=log
http://svn.apache.org/viewvc/hive/trunk/ql/src/java/org/apache/hadoop/hive/ql/udf/UDFType.java?r1=1074393&r2=1195577&diff_format=h

There is no code comments and no mention of it in the ticket.

Could someone please provide some information such as....

https://issues.apache.org/jira/browse/HIVE-1994

So people will know how to use this feature?
