Hi Aditya,
One can store the data in HDFS either directly or through HBase. Data consumer reads/accesses the data in HDFS randomly using HBase. HBase sits on top of the HDFS and provides read and write access.
The data is already store in hdfs by hbase or vice versa.

To upload the bulk data into Hbase directory, you can use data migratory tool like sqoop to directly upload the data into hbase format.

Hope this helps.
Thanks.
