I am trying to group my data and store in hdfs with a folder for each 'name' and subfolders for each 'YearMonth' under each name folder.

Input:
(Date)            (name)     (col3)     (col4)
2015-02-02    abc              y          z
2016-01-02    xyz              i            j
2015-03-02    abc              f          b
2015-02-06    abc              y          z
2016-03-02    xyz              a          q
    
Expected out in hdfs:
abc folder
    ->201502 subfolder
           2015-02-02    abc              y          z
           2015-02-06    abc              y          z
    ->201503 subfolder
           2015-03-02    abc              f           b
xyz folder
    ->201601
          2016-01-02    xyz              i            j
    ->201603
          2016-03-02    xyz              a          q

I am not sure of how to use the Multistorage option on Name column after grouping the tuples by date.

Any help is appreciated.
