Learn Hadoop by working on interesting Big Data and Hadoop Projects Each stage is sequential and depend on each other.

Each job is divided into smaller set of tasks called stages.

Fundamental unit of the Job that is run by the executor.

It uses worker node’s resources and memory.

Process launched on the worker node that runs tasks.

This is the node that runs the application program on the machine which contains the data.

It is only responsible for job submission.

#INSTALL SPARK UBUNTU DRIVER#

Client – Here driver is not part of the cluster.

Cluster – Here driver runs inside the cluster.

It can be standalone spark manager, Apache Mesos, YARN, etc.

This is an external service which manages resources needed for the job execution.

This is the process which starts complete execution.

It acts as the entry point of the application.

User program and its dependencies are bundled into the application jar so that all of its dependencies are available to the application.

But before we start writing any java application let’s get familiar with few terms of spark application: Next we will write a basic Scala application to load a file and then see its content on the console. Get FREE Access to Data Analytics Example Codes for Data Cleaning, Data Munging, and Data Visualization Now in the launched spark-shell, let’s check the Spark’s Scala shell version by the following command sc.version To check let’s launch the Spark Shell by the following command: spark-shell We have successfully configured spark in standalone mode. bashrc file by the command source ~/.bashrc

#INSTALL SPARK UBUNTU UPGRADE#

Make a softlink to the actual spark directory (This will be helpful for any version upgrade in future) ln -s spark-1.5.2-bin-hadoop2.4 spark Select the spark distribution as shown in the below snapshot:ĭownload Spark-1.6.1 from the shown link or use the following command to download spark wget ĭecompress the Spark file into /DeZyre directory tar –xvf spark-1.6.1-bin-hadoop2.4.tgz –C /DeZyre We would be configuring Spark to run in standalone mode, hence we would download prebuilt binary of Spark which is precompiled against Hadoop. Go to page.

#INSTALL SPARK UBUNTU INSTALL#

Now, we would install Spark on the machine.

You can check it using the command java -version. This would install Java 8 in the machine. Sudo update-alternatives -set javac /DeZyre/jdk1.8.0_51/bin/javac Sudo update-alternatives -set jar /DeZyre/jdk1.8.0_51/bin/jar Sudo update-alternatives -install /usr/bin/jps jps /opt/jdk1.8.0_51/bin/jps 1 Sudo update-alternatives -install /usr/bin/javac javac /opt/jdk1.8.0_51/bin/javac 1 Sudo update-alternatives -install /usr/bin/java java /opt/jdk1.8.0_51/bin/java 1

#INSTALL SPARK UBUNTU UPDATE#

Update the available files in your default java alternatives so that java 8 is referenced for all application sudo update-alternatives -install /usr/bin/jar jar /opt/jdk1.8.0_51/bin/jar 1 Decompress the downloaded tarball of java jdkĥ.Wget -no-cookies -no-check-certificate -header "Cookie: gpw_e24=http%3A%2F% oraclelicense=accept-securebackup-cookie"" Download java jdk(This tutorial uses Java 8 however Java 7 is also compatible ).This tutorial has used “ /DeZyre” directory Change to the directory where you wish to install java.Note: This tutorial uses an Ubuntu box to install spark and run the application.

Let’s install java before we configure spark. Java should be pre-installed on the machines on which we have to run Spark job. Standalone mode is good to go for a developing applications in spark. Driver runs inside an application master process which is managed by YARN on the cluster.Both driver and worker nodes runs on the same machine. Simplest way to deploy Spark on a private cluster.Along with that it can be configured in local mode and standalone mode. Spark can be configured with multiple cluster managers like YARN, Mesos etc. This tutorial presents a step-by-step guide to install Apache Spark.
