First of all you can not rename a directory of file in hadoop/HDFS
but you can do :
Hadoop fs -mv /warehouse/bigdata/data/test /warehouse/bigdata/data/test_d

If you want to do this for all your 200 HDFS part files then you have to write Shell/bash script to do this in recursive loop.
just write above hadoop command in shell loop.
