Scala and Java users can include Spark in their projects using its Maven coordinates and Python users can install Spark from PyPI. If you’d like to build Spark from source, visit Building Spark. Spark runs on both Windows and UNIX-like systems (e.g. Linux, Mac OS), and it should run on any platform that runs a supported version of Java. Note: Do not attempt to uninstall Java by removing the Java tools from /usr/bin. This directory is part of the system software and any changes will be reset by Apple the next time you perform an update of the OS. Install the older release of Java (Java 8 Update 161) 7. Next, visit the Oracle Java archive.

Apache Spark is a unified analytics engine for large-scale data processing.It provides high-level APIs in Java, Scala, Python and R,and an optimized engine that supports general execution graphs.It also supports a rich set of higher-level tools including Spark SQL for SQL and structured data processing, MLlib for machine learning, GraphX for graph processing, and Structured Streaming for incremental computation and stream processing.
Security in Spark is OFF by default. This could mean you are vulnerable to attack by default.Please see Spark Security before downloading and running Spark.
Get Spark from the downloads page of the project website. This documentation is for Spark version 3.0.1. Spark uses Hadoop’s client libraries for HDFS and YARN. Downloads are pre-packaged for a handful of popular Hadoop versions.Users can also download a “Hadoop free” binary and run Spark with any Hadoop versionby augmenting Spark’s classpath.Scala and Java users can include Spark in their projects using its Maven coordinates and Python users can install Spark from PyPI.

Spark runs on both Windows and UNIX-like systems (e.g. Linux, Mac OS), and it should run on any platform that runs a supported version of Java. This should include JVMs on x86_64 and ARM64. It’s easy to run locally on one machine — all you need is to have
java
installed on your system PATH
, or the JAVA_HOME
environment variable pointing to a Java installation.Spark runs on Java 8/11, Scala 2.12, Python 2.7+/3.4+ and R 3.5+.Java 8 prior to version 8u92 support is deprecated as of Spark 3.0.0.Python 2 and Python 3 prior to version 3.6 support is deprecated as of Spark 3.0.0.For the Scala API, Spark 3.0.1uses Scala 2.12. You will need to use a compatible Scala version(2.12.x).
For Java 11,
-Dio.netty.tryReflectionSetAccessible=true
is required additionally for Apache Arrow library. This prevents java.lang.UnsupportedOperationException: sun.misc.Unsafe or java.nio.DirectByteBuffer.(long, int) not available
when Apache Arrow uses Netty internally.Spark comes with several sample programs. Scala, Java, Python and R examples are in the
examples/src/main
directory. To run one of the Java or Scala sample programs, usebin/run-example <class> [params]
in the top-level Spark directory. (Behind the scenes, thisinvokes the more generalspark-submit
script forlaunching applications). For example,You can also run Spark interactively through a modified version of the Scala shell. This is agreat way to learn the framework.
The
--master
option specifies themaster URL for a distributed cluster, or local
to runlocally with one thread, or local[N]
to run locally with N threads. You should start by usinglocal
for testing. For a full list of options, run Spark shell with the --help
option.Spark also provides a Python API. To run Spark interactively in a Python interpreter, use
bin/pyspark
:Example applications are also provided in Python. For example,
Spark also provides an R API since 1.4 (only DataFrames APIs included).To run Spark interactively in an R interpreter, use
bin/sparkR

Example applications are also provided in R. For example,
The Spark cluster mode overview explains the key concepts in running on a cluster.Spark can run both by itself, or over several existing cluster managers. It currently provides severaloptions for deployment:
- Standalone Deploy Mode: simplest way to deploy Spark on a private cluster
Programming Guides:
- Quick Start: a quick introduction to the Spark API; start here!
- RDD Programming Guide: overview of Spark basics - RDDs (core but old API), accumulators, and broadcast variables
- Spark SQL, Datasets, and DataFrames: processing structured data with relational queries (newer API than RDDs)
- Structured Streaming: processing structured data streams with relation queries (using Datasets and DataFrames, newer API than DStreams)
- Spark Streaming: processing data streams using DStreams (old API)
- MLlib: applying machine learning algorithms
- GraphX: processing graphs

Update: Please see our Java Support in Safari 12 article for the latest information on Java support in Safari on macOS. The option to allow plug-ins described below is no longer supported by Safari.
No matter which web browser you use on your computer, you will need the Java plug-in from Oracle in order to view content that uses Java, such as Java applets. The Safari web browser on Mac from Apple is no exception. Java applets are common on the Internet. It is important, therefore, to know how to enable and disable Java in Safari on Mac if it is your web browser of choice.
First, please be certain the version of Java on your computer is current. Once you have verified Java is installed on your computer, please follow the instructions below to learn how to enable or disable Java in Safari on Mac.
1. Launch the Safari application, and click the Safari file menu. Select Preferences from the drop-down menu.
2. The Preferences dialog will launch in a new window. Click the Security icon.
Java Jdk Latest Version For Mac
To enable Internet plug-ins, including Java, to load in Safari, check the Internet Plugins: Allow Plug-ins check box. Unlike Safari on Windows, there is no individual check box for Enable Java for Safari on Mac.
3. When you encounter Java content in Safari, Safari will block the content from loading. You will see a notification in the browser window where the Java content would otherwise load:
4. Click the right-arrow in the notification. A Do you want to trust the website… dialog will display.
Latest Java Version Mac
In this case, we visited the Java.com web site to load a test Java applet. Since we trust the web site, we clicked the Trust button to allow java.com to use the Java plug-in. When we re-visit the Java content on this web site, the Java content will now display.
5. You can manage your trusted web sites, and choose degrees of trust, by returning to the Security settings of Safari’s Preferences window. Adjacent to the Internet Plugins: Allow Plug-ins check box, click the Website Settings… button.
A new dialog will launch. The dialog displays all of the Internet plug-ins currently installed. To manage the web sites you have trusted to use the Java plug-in, click Java in the left navigation pane. The list of web sites you have already trusted will display.
Use the pull-down menu adjacent to the web site in the list to choose a level of trust you want to extend to this site. You may choose from Ask, Block, Allow or Allow Always (or Run In Unsafe Mode). You may delete a web site from this list by highlighting it with your mouse, and clicking the minus button at the bottom of the list.
