Lefty Leverenz commented on HIVE-15982:
---------------------------------------
Doc note: The width_bucket function needs to be documented in the UDFs wiki.
I'm not sure which section it belongs in -- perhaps UDAFs.
* [Hive Operators and UDFs |
https://cwiki.apache.org/confluence/display/Hive/LanguageManual+UDF]
Added a TODOC3.0 label.

> Support the width_bucket(wbo, wbb1, wbb2, wbc) which returns an integer
> between 0 and wbc+1 by mapping wbo into the ith equally sized bucket made by
> dividing wbb1 and wbb2 into equally sized regions. If wbo < wbb1, return 1,
> if wbo > wbb2 return wbc+1. Reference: SQL standard section 4.4.
