Make sure you have zookeeper host and port defined in hbase-site.xml. The
error looks like they are not defined.
<description>Property from ZooKeeper's config zoo.cfg.
The port at which the clients will connect.
<description>Comma separated list of servers in the ZooKeeper Quorum.
For example, "host1.mydomain.com,host2.mydomain.com,host3.mydomain.com".
By default this is set to localhost for local and pseudo-distributed modes
of operation. For a fully-distributed setup, this should be set to a full
list of ZooKeeper quorum servers. If HBASE_MANAGES_ZK is set in
this is the list of servers which we will start/stop ZooKeeper on.

This could be a sign that the server has too many connections (30 is the default). Consider inspecting your ZK server logs for that error and then make sure you are reusing HBaseConfiguration as often as you can. See HTable's javadoc for more information.
