PySpark is the Python API for Spark.

Public classes:

  - L{SparkContext<pyspark.context.SparkContext>}
      Main entry point for Spark functionality.
  - L{RDD<pyspark.rdd.RDD>}
      A Resilient Distributed Dataset (RDD), the basic abstraction in Spark.
  - L{Broadcast<pyspark.broadcast.Broadcast>}
      A broadcast variable that gets reused across tasks.
  - L{Accumulator<pyspark.accumulators.Accumulator>}
      An "add-only" shared variable that tasks can only add values to.
  - L{SparkConf<pyspark.conf.SparkConf>}
      For configuring Spark.
  - L{SparkFiles<pyspark.files.SparkFiles>}
      Access files shipped with jobs.
  - L{StorageLevel<pyspark.storagelevel.StorageLevel>}
      Finer-grained cache persistence levels.

Spark SQL:
  - L{SQLContext<pyspark.sql.SQLContext>}
      Main entry point for SQL functionality.
  - L{SchemaRDD<pyspark.sql.SchemaRDD>}
      A Resilient Distributed Dataset (RDD) with Schema information for the data contained. In
      addition to normal RDD operations, SchemaRDDs also support SQL.
  - L{Row<pyspark.sql.Row>}
      A Row of data returned by a Spark SQL query.

Hive:
  - L{HiveContext<pyspark.context.HiveContext>}
      Main entry point for accessing data stored in Apache Hive..
