Basics
Spark’s shell provides a simple way to learn the API, as well as a powerful tool to analyze data interactively.It is available in either Scala (which runs on the Java VM and is thus a good way to use existing Java libraries)or Python. Start it by running the following in the Spark directory:
More on Dataset Operations
Dataset actions and transformations can be used for more complex computations. Let’s say we want to find the line with the most words:
Caching
Spark also supports pulling data sets into a cluster-wide in-memory cache. This is very useful when data is accessed repeatedly, such as when querying a small “hot” dataset or when running an iterative algorithm like PageRank. As a simple example, let’s mark our linesWithSparkdataset to be cached:
Suppose we wish to write a self-contained application using the Spark API. We will walk through asimple application in Scala (with sbt), Java (with Maven), and Python (pip). Other dependency management tools such as Conda and pip can be also used for custom classes or third-party libraries. See also Python Package Management.
Congratulations on running your first Spark application! 1. For an in-depth overview of the API, start with the RDD programming guide and the SQL programming guide, or see “Programming Guides” menu for other components. 2. For running applications on a cluster, head to the deployment overview. 3. Finally, Spark includes several samples in the examp...
PySpark users can use virtualenv to manage Python dependencies in their clusters by using venv-pack in a similar way as conda-pack. A virtual environment to use on both driver and executor can be created as demonstrated below. It packs the current virtual environment to an archive file, and it contains both Python interpreter and the dependencies.
Mar 1, 2016 · The basic idea is. Create a virtualenv purely for your Spark nodes. Each time you run a Spark job, run a fresh pip install of all your own in-house Python libraries. If you have set these up with setuptools, this will install their dependencies. Zip up the site-packages dir of the virtualenv.
