---------------------------------
+1 for this issue.
Tajo can support various types of storages by abstracting the storage layer.
> Generic StorageHandler to provide common storage methods

> Key: TAJO-337
> URL: https://issues.apache.org/jira/browse/TAJO-337
> Project: Tajo
> Issue Type: Improvement
> Components: catalog, storage
> Reporter: Hyunsik Choi
> Assignee: Hyunsik Choi
> Fix For: 1.0-incubating
>
>
> 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.
