Lefty Leverenz commented on HIVE-8114:
--------------------------------------
Doc note: The wiki needs to be updated. Currently it says "log(DOUBLE base,
DOUBLE a) -- Return the base-base logarithm of the argument d. Instead of
DOUBLE this UDF also takes DECIMAL, both types can be mixed." Hmm ... better
change "d" to "a" in that.
Since this was broken previously, can we just delete "both types can be mixed"
without giving version & JIRA information?

A release note would also be good.
