> Currently, the load runs sequentially, which can be a problem for loading a
> large directory.
> The following syntax should work:
> LOAD OVERWRITE DIRECTORY INTO TABLE <T> PARTITION <P>;
> The user should be able the total number of mappers. For now, a single mapper
> per file is OK.
> We can add support for parallelism within a file later
