Hi Xuelin, What version of Spark are you using?
Thanks, Daoyuan From: Xuelin Cao [mailto:xuelincao2...@gmail.com] Sent: Tuesday, January 20, 2015 5:22 PM To: User Subject: IF statement doesn't work in Spark-SQL? Hi, I'm trying to migrate some hive scripts to Spark-SQL. However, I found some statement is incompatible in Spark-sql. Here is my SQL. And the same SQL works fine in HIVE environment. SELECT if(ad_user_id>1000, 1000, ad_user_id) as user_id FROM ad_search_keywords What I found is, the parser reports error on the "if" statement: No function to evaluate expression. type: AttributeReference, tree: ad_user_id#4 Anyone have any idea about this?
