HBase is not a relational database, so many things that are in a SQL database dont exist.
eg: - sequences - secondary declarative keys - joins - advance query features such as order by, group by - operators of any kind Given conventions (eg: naming of index tables), it might be possible to semi-automatedly convert data, but it might not efficiently take advantage of HBase's unique schema-less design. I suggest you have a look at the Google's bigtable paper, as it has the same underlying model that HBase does. Good luck!
