Hi Deepak, We don't support Hive's storage handler API - we have our own HBase support that was use for HBase tables. We also have similar support for Kudu tables. To add equivalent support system you'd need to add frontend Java support for planning queries against that table type and backend C++ support for scanning the data. This kind of thing would be a pretty big change so there would need to be buy-in from the community.
We also have a Java data source API that lets you write a Java class that scans an arbitrary data source. That is easier to use but has limitations (only executes on a single node, performance is worse than other table types.
