Sc = SparkContext(master="local", appName="Spark Demo") I am experiencing some issues executing a simple python program:įrom pyspark import SparkConf, SparkContext # Initialize PySpark to predefine the SparkContext variable 'sc'Įxecfile(os.path.join(spark_home, "python/pyspark/shell.py"))
INSTALL APACHE SPARK PYTHON MAC INSTALL
# You may need to change the version number to match your install # Add the spark python sub-directory to the path If not "pyspark-shell" in pyspark_submit_args: pyspark_submit_args += " pyspark-shell" Pyspark_submit_args = os.environ.get("PYSPARK_SUBMIT_ARGS", "") If os.path.exists(spark_release_file) and "Spark 1.4" in open(spark_release_file).read(): Spark_release_file = spark_home + "/RELEASE" # the end of the 'PYSPARK_SUBMIT_ARGS' environment variable # If Spark V1.4.x is detected, then add ' pyspark-shell' to Spark_home = os.environ.get("SPARK_HOME")
INSTALL APACHE SPARK PYTHON MAC CODE
Here is the code : # Configure the necessary Spark environment So I adapted the script '00-pyspark-setup.py' for Spark 1.3.x and Spark 1.4.x as following, by detecting the version of Spark from the RELEASE file. To do so you have to add following env variables:įor Spark 1.4.x we have to add 'pyspark-shell' at the end of the environment variable "PYSPARK_SUBMIT_ARGS". You can also force pyspark shell command to run ipython web notebook instead of command line interactive interpreter.
Run ipython $ jupyter-notebookĮxecfile(os.path.join(os.environ, 'python/pyspark/shell.py')) Thus, the easiest way will be to run pyspark init script at the beginning of your notebook manually or follow alternative way. It seems that it is not possible to run various custom startup files as it was with ipython profiles. Unrecognized alias: '-profile=pyspark ', it will probably have no effect. WARNING | You likely want to use `jupyter notebook ` in the future WARNING | Subcommand `ipython notebook ` is deprecated and will be removed in future versions.
