Data Storage: The next step after data ingestion is to store it in HDFS or a NoSQL database such as HBase. NoSQL, for example, may not be appropriate for message queues. Every map/reduce action carried out by the Hadoop framework on the data nodes has access to cached files. This is due to a NameNode performance problem.
