The cause: This error happens because Zookeeper won’t stay live if the host computer or virtual machine is put to sleep.

Solution: You can fix this error by starting Zookeeper and then run Hbase-shell:

{HBASE_HOME}/bin/hbase-daemons.sh {start,stop} zookeeper

Then you need to check this property in hbase-env.sh:

# Tell HBase whether it should manage its own instance of Zookeeper or not.
export HBASE_MANAGES_ZK=false
