Java client connection to HBase 0.20.1 problem

Hi to everyone in the forum!

I'm getting started with HBase 0.20.1 and I'm trying to prepare dev
environment for web application development based on HBase as storage.

In my test desktop java application I'm getting console output like this:

Re: Java client connection to HBase 0.20.1 problem

Add the following in your /etc/hosts

<ip address> <hostname>

That might be the problem

Re: Java client connection to HBase 0.20.1 problem

Restart the network interfaces after you edit the hosts file:

sudo /etc/init.d/networking restart

New Filter Functionality Required [was: Re: Problem using RowFilter]

Hello,
I am back to where I am going to need the functionality I have described 
below - basically a SCVF that works on all versions. I was wondering if 
I may go ahead and open an issue for this and begin to contribute some 
code. Granted, I will have to do some digging to get my head around the 
filtering at the moment. If that is fine, then I will go ahead and do so 
and post in JIRA once I have something working.
Thanks
J

Please do.  Let us know if we can help out.  Make sure you get latest code.
Some fixes have gone in for filters recently.
