Are you using the SQLContext? I think the HiveContext is recommended. Cheng Hao

I tried to use the built-in Hive Function to extract the hour from timestamp in spark sql, but got : "java.util.NoSuchElementException: key not found: hour" How should I extract the hour from timestamp? And I am very confusing about which functions I could use in Spark SQL. Is there any list of available functions except http://spark.apache.org/docs/1.2.0/sql-programming-guide.html#compatibility-with-apache-hive ? Thanks, Wush
