Question

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!

Answer 1

I think first of all you need to understand Why are you using HBase and what is column oriented approach.
You will see everywhere that while creating a design for HBase you will create a
column and then a

column family 

Now the thing is you have to keep in mind that HBase is for very large scale data and when you need mapreduce jobs and fast retrievals.I can;t cover HBase column oriented approach here but i suggest you this link.I hope it will be helpful for you 🙂
feel free to ask question if you have any confusion
