-----------------------------------

             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
{code}
