Hi,

It's difficult to know what the issue is without knowing what is in your hbase table.  I would suggest first using the 'scan' function in the Hbase shell, to see if you can access records starting with row number 20001.  Here's a link to a reference guide for the shell commands  http://learnhbase.wordpress.com/2013/03/02/hbase-shell-commands/
