Description

Currently for sql like – select count(distinct seller_id, lstg_format_name) from test_kylin_fact

Will result –
org.eigenbase.sql.validate.SqlValidatorException <init>
SEVERE: org.eigenbase.sql.validate.SqlValidatorException: Invalid number of arguments to function 'COUNT'. Was expecting 1 arguments

Could optiq support multiple parameters in count(distinct ...) ?
