Mostly HMaster is not running. Enter the sudo jps command in your Terminal and check if HMaster is running or not.

If HMaster is not running, run the following command to start it:

sudo su
cd /usr/lib/hbase-0.96.2-hadoop2
bin/start-hbase.sh

Next, to list the tables, first open hbase shell and then list the tables. Use the following commands:

hbase shell 
list
