I am trying to create Java application that convert MYSQL database to NOSQL Hbase database .
So far it read the data from mysql and insert it to hbase correctely
But now i'am trying to handle relationship between tables of MYSQL,
and i understand if there are relationship you should add one of table as super column family .
I looked in apatch website documentation i couldn't find anything.
Any ideas ?

Column family has nothing to do with relationship. In contrast you have to correctly create inversed indexes via row key design which may allow to effectively O(1) retrieve data from one table by knowing key from another. Or to avoid join try to store all data in one row. Any tool that provides SQL interface for HBase spawns jobs which take time to start and execute. HBase is fast if you do Get operation or Scan successive rows. Hope this was useful.
Update
Regarding more details about column families check out great book Architecting HBase Applications
