Impala Jdbc throws exception where Impala Hue works fine

Hi,

The query "select count(*) from sample_07 where exists(select code from sample_08 where sample_08.salary = sample_07.salary);
" works fine in Impala Hue. When it is executed through JDBC, I am getting the following exception

Exception in thread "main" java.sql.SQLException: [Simba][ImpalaJDBCDriver](500320) Error during translation: code 42000, type Syntax error or access violation, message AEExistsPredicate is not supported

Maybe you could UseNativeQuery?
