Hello! I've just blogged on design of table model for recommendations stored in HBase. http://datacentric.pl/blog/2016/03/design-hbase-data-model-recommendations/ I hope it will be useful for users approaching to development of a recommendation engine using HBase.
I would be happy of any comment on ideas presented in the post and if there is something wrong don't hesitate to correct me. -- Kind regards/ Pozdrawiam, Wojciech Indyk http://datacentric.pl
