I am trying to use Hbase as event server with predictionIO. Which is working 
fine as expected.
But I am getting error while point Hbase installed on a separate machine other 
than predictionIO.

As per the understanding, I have done the below steps:

1. Copied the hbase conf folder (from the machin on Hbase is running) that 
contains hbase-site.xml to any folder on prediction io server on some path i.e. 

2. Updated HBASE_CONF_DIR in to point to the path of copied folder 




3. Updated the property "hbase.zookeeper.quorum" in hbase-site.xml on local 
copied folder i.e. 
"/home/ubuntu/hbasePrediction-io/PredictionIO-0.9.6/hbase/conf" i.e.


    <value><Master public DNS></value>


But I am getting the below error.
