> catalog.getFunction(name) returns wrong result for a permanent function

> Key: SPARK-17996
> URL: https://issues.apache.org/jira/browse/SPARK-17996
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Reporter: Herman van Hovell

> The catalog returns a wrong result, if we lookup a permanent function without
> specifying the database. For example:
> {noformat}
> scala> sql("create function fn1 as
> 'org.apache.hadoop.hive.ql.udf.generic.GenericUDFAbs'")
> res0: org.apache.spark.sql.DataFrame = []
> scala> spark.catalog.getFunction("fn1")
> res1: org.apache.spark.sql.catalog.Function = Function[name='fn1',
> className='org.apache.hadoop.hive.ql.udf.generic.GenericUDFAbs',
> isTemporary='true']
> {noformat}
> It should not return that this function is temporary and define a database.
