---------------------------------------
Summary: SQL's floor() returns DOUBLE
Key: SPARK-10724
URL: https://issues.apache.org/jira/browse/SPARK-10724
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 1.5.0
Reporter: Simeon Simeonov
Priority: Critical
This is a change in behavior from 1.4.1 where {{floor}} returns a BIGINT.
{code}
scala> sql("select floor(1)").printSchema
root
|-- _c0: double (nullable = true)
{code}
In the [Hive Language
Manual|https://cwiki.apache.org/confluence/display/Hive/LanguageManual+UDF]
{{floor}} is defined to return BIGINT.
This is a significant issue because it changes the DataFrame schema.
I wonder what caused this and whether other SQL functions are affected.
