> Insert statements create files of format ending with 0000_0, 0001_0 etc.
> However, the load data uses the input file name. That results in inconsistent
> naming convention which makes SMB joins difficult in some scenarios and may
> cause trouble for other types of queries in future.
> We need consistent naming convention.
> For bucketed table, hive relies on user to name the files matching the bucket
> in non-strict mode. Hive assumes that the data belongs to same bucket in a
> file. In strict mode, loading bucketed table is disabled.
> This will likely affect most of the tests which load data which is pretty
> significant.
