>
> Test framework masks output of "Path -> Alias" for explain extended. This
> makes it impossible to verify the output is right.
> Design is to add a new entry "Truncated Path -> Alias" to MapredWork. It has
> the same content as "Path -> Alias" except the prefix including file schema
> and temp dir is removed. The following config will be used for prefix-removal:
> METASTOREWAREHOUSE("hive.metastore.warehouse.dir", "/user/hive/warehouse"),
> This will keep "Path -> Alias" intact and also test it's result is right.
> The first use case is to verify list bucketing query's result is right.
