You can have your cake and eat it too, you can have your smart phone and tablet connected to a Hadoop cluster, all the while still being able to use the tablet on your commute to work or in the classroom. You can save money on data storage by using a shared host and dynamic content store, and dynamically provision and expand your cluster. Your data is always safe and available no matter how fast the cluster is, and you never have to worry about losing your data. In this session, You will learn how to set up your own DynamicCluster, connect to it using the Hdfs API and start writing Spark Streaming Applications. We will show you how to ingest your data into a cluster, and then actually process and write it to your HDFS using built-in Spark Streaming Libraries.


The new spark platforms map your entire history from the past to the present, and provide powerful facilities for storage and retrieval of a wide range of unstructured data. Spark, datasets, and analytics you can explore and query at any scale, with better performance, easier management and smarter insights.


Youll have to carefully organise and manage the storage of data for big data applications. Different organisations have very different requirements and varying costs associated with storage. Data compression is extremely important for many applications of big data. Spark Streaming features an optimised compression which can be used to save up to 1 million GB of data per day on a single server and minimise the amount of data that is required to be transported.
