Pre-requestites:

• Kafka topic and producer has to be Up and running.
• Hbase thrift server and zookeeper should be running. Because the spark program connects to Hbase thrift server via zookeeper.
• Hbase table and Column family has to be created. (Refer hbase.ddl) +=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=
