> 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 non-bucketed table, hive renames all the files regardless of how they
> were named by the user.
> 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 due to which it is further divided into two subtasks for smoother
> merge.
> For existing tables in customer database, it is recommended to reload
> bucketed tables otherwise if customer tries to run SMB join and there is a
> bucket for which there is no split, then there is a possibility of getting
> incorrect results. However, this is not a regression as it would happen even
> without the patch.
> With this patch however, and reloading data, the results should be correct.
> For non-bucketed tables and external tables, there is no difference in
> behavior and reloading data is not needed.
