• Install zookeeper and start it by running zkServer start

Once you have everything installed set the following property in $HBASE_HOME/conf/hbase-site.xml

 <property>
    <name>hbase.coprocessor.user.region.classes</name>
    <value>org.locationtech.geomesa.hbase.coprocessor.GeoMesaCoprocessor</value>
