MapReduce (Hadoop): A basic implementation of table in Hive or HBase
===

I have been reading on Hadoop file system and trying to understand what it is. I have a basic understanding. I know RDBMS quite well, what I am struggling to understand is how a simple table can be implemented in say for example HBase.

From a Cloudera free tutorial, I learnt that HBase is column oriented, how do you implement a column oriented table (is it called a table?)?

How do you implement a simple users table with columns id, username, password (or can you not do something like this?)? 

Thanks!
