Jihoon Son commented on TAJO-337:
---------------------------------

+1 for this issue.
Tajo can support various types of storages by abstracting the storage layer.

> Currently, Tajo uses HDFS as a primary storage. But, as a data warehouse system, Tajo
should easily support various data sources.
> For this, I propose a generic storage handler interface that provides common storage
methods:
> * splitting input data
> * finding a cluster node which is nearest neighbor to data
> * accessing catalog
> * creating a table
> * removing a table
> The above methods are derived from query proecssing mechanism on data sets stored in
HDFS.
> Later, we can add easily storage handlers for HBase or other data sources.
