             Summary: Issue using table alias in Spark SQL case statement
                 Key: SPARK-13491
                 URL: https://issues.apache.org/jira/browse/SPARK-13491
             Project: Spark
          Issue Type: Bug
            Reporter: Tanmay Deshpande


I am trying to run a Hive query from Spark SQL doing so when I use case statements in select. I get an error saying 

16/02/25 15:19:30 INFO audit: ugi=admin1	ip=unknown-ip-addr	cmd=get_table : db=default tbl=employee2	
Exception in thread "main" org.apache.spark.sql.AnalysisException: cannot resolve 'employee1.id' given input columns salary, name, name, salary, id, id; line 1 pos 18

My Query in Spark is 
   val sqlStatement = s"select case when (employee1.id = employee2.id and concat(employee1.*) = concat(employee2.*) ) then 'NoChange' end from employee1 full outer join employee2 on employee1.id = employee2.id";
