Here, we get in touch with flatMap to remodel a Dataset of traces to a Dataset of terms, then Mix groupByKey and rely to compute the for each-term counts during the file as being a Dataset of (String, Prolonged) pairs. To collect the phrase counts within our shell, we are able to get in touch with accumulate:

The textFile strategy also requires an optional next argument for controlling the volume of partitions from the file. By default, Spark results in a single partition for every block of the file (blocks being 128MB by default in HDFS), but You can even ask for a better range of partitions by passing a larger benefit. Note that You can't have less partitions than blocks.
