I know that this post is quite old but i was searching something about HBase myself and came across with it.
Well i don’t know if this is the best way to do it, but you can definitely use the scripting option HBase gives you. Just open a shell (preferably go to the directory bin of HBase) and run
echo "scan 'foo'" | ./hbase shell > myText
where foo is the name of the table you want to scan. If you then open myText you will see the results in there. Hope i helped!
