-----------------------------------
Summary: Rename precision UDAF because it is reserved keyword of
Hive
Key: HIVEMALL-140
URL: https://issues.apache.org/jira/browse/HIVEMALL-140
Project: Hivemall
Issue Type: Bug
Reporter: Makoto Yui
Assignee: Takuya Kitazawa
Priority: Critical
`drop temporary function if exists precision;` fails on Hive v2.2.0 or later
because `precision` became a reserved keyword from hive v2.2.0.
https://cwiki.apache.org/confluence/display/Hive/LanguageManual+DDL#LanguageManualDDL-Keywords,Non-reservedKeywordsandReservedKeywords
So, we need to revise UDF name.
{code}
precision => precision_at
recall => recall_at
