Yes it is possible:
hadoop fs -mkdir /hdfs_path/'cust_id>1000'
I tested it and works, then you can store data in this directory .
for concat function you do simple:
insert into your_table_partionned PARTITION (path_xxx)
select attr,id, concat ('/data1/customer/', id) as path_xxx from
your_table
where id <1000
......
Cdt.
