Create table in hbase

Question

I am new to hbase and hadoop. Anyway, I managed to create a hadoop cluster consisting of 3 machines. Now I need help creating a database.

I have a table "comments" contains the fields:

• user ID
• comments
• comments on comments (which may be more than one) and a status field for the same,

Can someone help me build the same with hbase / shell?
