Hi, Here is the test method I've ignored due to Connection Refused problem failure:
https://github.com/kamaci/gora/blob/master/gora-hbase/src/test/java/org/apache/gora/hbase/mapreduce/TestHBaseStoreWordCount.java#L65 I've implemented a Spark backend for Apache Gora as GSoC project and this is the latest obstacle that I should solve. If you can help me, you are welcome.
