Hive Storage Handler to replace HDFS with custom store

Hi All,

Hive by default queries onto HDFS. If I implement Hive Storage Handler for my store with
1. input format
2. output format
3. AbstractSerDe

Hive queries will then store and retrieve from my store instead of HDFS, Is this understanding correct? or any other changes needed in Hive code?

Regards,
Amey
