PySpark Tutorial

• PySpark is the Python API for Spark.
• The purpose of PySpark tutorial is to provide basic distributed algorithms using PySpark.
• PySpark has an interactive shell ($SPARK_HOME/bin/pyspark) for basic testing and debugging and is not supposed to be used for production environment.
• You may use $SPARK_HOME/bin/spark-submit command for running PySpark programs (may be used for testing and production environemtns)
