hbase

I have a single node hadoop machine in which hbase is running in the amazone ec2 instance. Due to some reason the server got restarted. So i need to start hadoop and hbase again. Then its working fine, but the old data in the hbase cannot be accessed through the web-servies.

While i use the shell command its working fine, i am getting the data.

So i created the scenario on my local server machine, but its working fine.

The version details are as follows. hadoop-0.20.2 hbase-0.90.5 apache-tomcat-7.0.30 in Amazon ec2 medium instance

And i use restful web-services with Orm-hbase to access data.
