it has nothing standalone or distributed mode. make sure setup working fine. can see regionserver , zookeeper not running. comment out line 127.0.1.1 ubuntu in /etc/hosts file , restart hbase. might have kill it.
p.s : since have hadoop configured , running fine, can run hbase in pseudo-distributed setup.
