Xiao Li updated SPARK-18430:
----------------------------
    Description: 
When the exception is an invocation exception during function lookup, we return a useless/confusing error message:

For example, 
{code}
      df.selectExpr("format_string()")
{code}
or 
{code}
      df.selectExpr("concat_ws()")
{code}

Below is the error message we got:
{code}
null; line 1 pos 0
org.apache.spark.sql.AnalysisException: null; line 1 pos 0
{code}

  was:
