You want to compute the depend of each phrase during the text file. Here's how to complete this computation with Spark RDDs:
Be aware that applying OAuth will not be essential for private applications. If you want your application for use by a 3rd-get together and not only for your very own instance of your Drift System, we suggest this bearer token method
(RDD), which is a group of things partitioned over the nodes from the cluster which might be operated on in parallel. RDDs are developed by setting up having a file while in the Hadoop file procedure (or any other Hadoop-supported file program), or an current Scala assortment in the motive force program, and reworking it. Users can also check with Spark to persist

Accumulators will not alter the lazy evaluation model of Spark. When they are staying updated inside an operation on an RDD, their price is simply current once that RDD is computed as Section of an motion.
