John Sichi commented on HIVE-1387:
----------------------------------
Speaking of wiki...can you also update this page with descriptions for
percentile, percentile_approx, variance, and histogram_numeric? And while you
are in there, might as well cover stddev since that has always been missing
too. Note that variance and stddev both have _pop and _samp versions.
http://wiki.apache.org/hadoop/Hive/LanguageManual/UDF
Just one-line descriptions are fine here...users can execute DESCRIBE to get
the details.
