I ingested data from the geowave-example, SimpleIngest.java. Then to view it from geoserver 2.6.1, I created a new geowave datastore in geoserver and gave the instance name and zookeeper server parameters. I was able to create the datastore and also create a new layer 'point'. However when I tried to preview the layer as OpenLayers, I am getting the error, Rendering process failed on the map. And the following exception on the console:
