             Summary: Emulate Hive type coercion in native reimplementations of Hive UDFs
                 Key: SPARK-2863
                 URL: https://issues.apache.org/jira/browse/SPARK-2863
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 1.0.0
            Reporter: William Benton


Native reimplementations of Hive functions no longer have the same type-coercion behavior as they would if executed via Hive.  As <a href="https://github.com/apache/spark/pull/1750#discussion_r15790970"> Michael Armbrust points out</a>, queries like {{SELECT SQRT("2") FROM src LIMIT 1}} succeed in Hive but fail if {{SQRT}} is implemented natively.

Spark SQL should have Hive-compatible type coercions for arguments to natively-implemented functions.
