It is designed to scale up from single servers to thousands of machines, each offering local computation and storage.

Rather than rely on hardware to deliver high-availability, the library itself is designed to detect and handle failures at the application layer, so delivering a highly-available service on top of a cluster of computers, each of which may be prone to failures.

Spark supports in-memory processing to boost the performance of big data analytics applications, but it can also perform conventional disk-based processing when data sets are too large to fit into the available system memory.

The RDD is designed in such a way so as to hide much of the computational complexity from users.

It aggregates data and partitions it across a server cluster, where it can then be computed and either moved to a different data store or run through an analytic model.

The user doesnt have to define where specific files are sent or what computational resources are used to store or retrieve files.

Scalas static types help avoid bugs in complex applications, and its JVM and JavaScript runtimes let you build high-performance systems with easy access to huge ecosystems of libraries.

Just one minor thing: I needed to reboot my machine in order for those Env variables to take effect.

It can run on clusters managed by Hadoop YARN, Apache Mesos, or by Sparks standalone cluster manager itself.

Here, in this post, we will learn how we can install Apache Spark on a local Windows Machine in a pseudo-distributed mode (managed by Sparks standalone cluster manager) and run it using PySpark ( Sparks Python API ).

Install Spark on Local Windows Machine To install Apache Spark on a local Windows machine, we need to follow below steps: Step 1 Download and install Java JDK 8 Java JDK 8 is required as a prerequisite for the Apache Spark installation.

Winutils Exe Download 32 Bit

JDK 8 Download As highlighted, we need to download 32 bit or 64 bit JDK 8 appropriately.

Once the file gets downloaded, double click the executable binary file to start the installation process and then follow the on-screen instructions.

Step 2 Download and install Apache Spark latest version Now we need to download Spark latest build from Apache Sparks home page.

The latest available Spark version (at the time of writing) is Spark 2.4.3.

The default spark package type is pre-built for Apache Hadoop 2.7 and later which works fine.

Next, click on the download spark-2.4.3-bin-hadoop2.7.tgz to get the.tgz file.

Winutils Exe Zip The Zipped

Download Apache Spark After downloading the spark build, we need to unzip the zipped folder and copy the spark-2.4.3-bin-hadoop2.7 folder to the spark installation folder, for example, C:Spark (The unzipped directory is itself a zipped directory and we need to extract the innermost unzipped directory at the installation path.).

Spark installation folder Step 3- Set the environment variables Now, we need to set few environment variables which are required in order to set up Spark on a Windows machine.

Also, note that we need to replace Program Files with Progra1 and Program Files (x86) with Progra2.

Step 5 Download and copy winutils.exe Next, we need to download winutils.exe binary file from this git repository.

Navigate to the hadoop- 2.7.1 folder (We need to navigate to the same Hadoop version folder as the package type we have selected while downloading the Spark build).

Go to the bin folder and download the winutils.exe binary file.

This is the direct link to download winutils.exe for Hadoop 2.7 and later spark build.

Copy this file into bin folder of the spark installation folder which is C:Sparkspark-2.4.3-bin-hadoop2.7bin in our case.

Step 6 Create hive temp folder In order to avoid hive bugs, we need to create an empty directory at C:tmphive.

Step 7 Change winutils permission Once, we have downloaded and copied the winutils.exe at the desired path and have created the required hive folder, we need to give appropriate permissions to the winutils.

In order to do so, o pen the command prompt as an administrator and execute the below commands.

Python can be downloaded from the official python website link.

Download Python Step 9 pip Install pyspark Next, we need to install pyspark package to start Spark programming using Python.

To do so, we need to open the command prompt window and execute the below command.

Below is a sample spark code written using Jupyter notebook.

He has implemented many end to end solutions using Big Data, Machine Learning, OLAP, OLTP, and cloud technologies.
