Hi,
I am using HBase 0.98.6.
I learned from this maillist before, that the recommended method to 'connect'
to HBase from client is to use HConnectionManager like this:
HConnection
con=HConnectionManager.createConnection(configuration);
s a good abstraction to control the life

more. But the important thing is that with the new style, you do not need
to worry anything about these since there is no implicit connection

Thanks, Enis,
Your reply is very clear, I finally understand it now.
Best Regards,
