MasterNotRunningException

Hi I am running the hbase VMWare sandbox MapR-Sandbox-For-Hadoop-3.1.0_VM.  I can access the control panel va browser.  On another liinux VM I have eclipse and the hbase client installed.  I have a java program where I want to create a hbase table but I cannot connect. 

As you can see below I get an ERROR

> ERROR client.HConnectionManager$HConnectionImplementation: Check the value configured in 'zookeeper.znode.parent'. There could be a mismatch with the one configured in the master.

and then

> timesorg.apache.hadoop.hbase.MasterNotRunningException: Retried 1 times

(see full stacktraace below).

My application uses

                System.setProperty("java.library.path", "/opt/mapr/lib");
  conf = HBaseConfiguration.create(); 
  conf.set("zookeeper.znode.parent", "/maprdemo");
  conf.set("hbase.zookeeper.quorum", "16.49.150.79");
  conf.set("hbase.zookeeper.property.clientPort", "5181");
  conf.set("hbase.client.retries.number", "2");
  admin = new HBaseAdmin(conf);
                System.out.println(admin.isMasterRunning());

POM includes

    <dependency>
    <groupId>org.apache.hbase</groupId>
    <artifactId>hbase</artifactId>
    <version>0.94.13-mapr-1401-m7-3.1.0</version>
   </dependency>
