> Even though bucket is empty, zero length file is being created in tez mode.
> steps to reproduce the issue:

> hive> set hive.execution.engine;
> hive.execution.engine=tez
> hive> drop table if exists emptybucket_orc;
> OK
> Time taken: 5.416 seconds
> hive> create table emptybucket_orc(age int) clustered by (age) sorted by
> (age) into 99 buckets stored as orc;
> OK
> Time taken: 0.493 seconds
> hive> insert into table emptybucket_orc select distinct(age) from
> studenttab10k limit 0;
