# hadoop# ubuntu Photo by AJ Robbie on Unsplash. For my Large-Scale Data Science course this semester, I need to use a single-node Hadoop system. The go-to option is the Cloudera Quickstart VM, but it doesn't support Java 8 and comes with Hadoop 2. Kotlin requires Java 8, so I decided to look for a way to setup a custom Ubuntu VM Install Hadoop and Run wordcount Job 1. First extract hadoop and put it to a folder. I used the easy Ubuntu way and let the download manager extract the file for me to a directory /srv/hadoop 2. Created a new user account for hadoop 3. Make sure hadoop could ssh to local host without needing a passwor

In this article, you'll learn to install a single-node Hadoop cluster backed by the Hadoop Distributed File System on Ubuntu (any version) and execute a simple Java program named Word count. Here's an intro to Hadoop. Apache Hadoop is an open-source software framework used for distributed storage and processing of dataset of big data using. 1) A machine with Ubuntu 14.04 LTS operating system installed. 2) Apache Hadoop 2.6.4 pre installed (How to install Hadoop on Ubuntu 14.04) Hadoop WordCount Example. Step 1 - Add all hadoop jar files to your java project. Add following jars * Hadoop comes with a set of demonstration programs. They are located in ~/hadoop/src/examples/org/apache/hadoop/examples/. One of them is WordCount.java which will. Now, run this command to copy the file input file into the HDFS. hadoop fs -put WCFile.txt WCFile.txt. Now to run the jar file by writing the code as shown in the screenshot. After Executing the code, you can see the result in WCOutput file or by writing following command on terminal. hadoop fs -cat WCOutput/part-00000. Attention reader

Hadoop comes with a set of demonstration programs. They are located in here. One of them is WordCount.java which will automatically compute the word frequency of all text files found in the HDFS directory you ask it to process. Follow the Hadoop Tutorial to run the example. Creating a working directory for your data Run the program! hadoop pipes -D hadoop.pipes.java.recordreader=true \ -D hadoop.pipes.java.recordwriter=true \ -input ncdc/sample.txt -output ncdc-out \ -program bin/max_temperature Verify that you have gotten the right output: hadoop dfs -text ncdc-out/part-00000 1949 111 1950 2 stop-dfs.sh - Stops the Hadoop DFS daemons. Executing WordCount Example in Hadoop standalone mode. When you download Hadoop, it comes with some existing demonstration programs and WordCount is one of them. Step-1. Creating a working directory for your data. create a directory and name it dft. $ mkdir dft $ cd dft ~/dft$ Step-2 <output directory> is the directory where the output of the Hadoop MapReduce WordCount program is going to be stored. This will start the execution of MapReduce job Now we have run the Map Reduce. In previous post we successfully installed Apache Hadoop 2.6.1 on Ubuntu 13.04. The main agenda of this post is to run famous mapreduce word count sample program in our single node hadoop cluster set-up. Running word count problem is equivalent to Hello world program of MapReduce world. MapReduce examples other than word count

$ ls -la total 20 drwxrwxr-x 3 ubuntu ubuntu 4096 Feb 10 17:27 . drwxr-xr-x 5 ubuntu ubuntu 4096 Feb 10 15:00. drwxrwxr-x 2 ubuntu ubuntu 4096 Feb 10 15:00 wordcount_classes -rw-rw-r-- 1 ubuntu ubuntu 3071 Feb 10 15:08 wordcount.jar -rw-rw-r-- 1 ubuntu ubuntu 2089 Feb 10 15:00 WordCount.java $ whoami ubuntu $ sudo su hdfs $ hadoop jar. Wordcount example: For wordcount example also we are using hadoop-mapreduce-examples-2.7.4.jar file. The wordcount example returns the count of each word in the given documents. Wordcount using Hadoop streaming (python) Here is mapper and reducer program for wordcount. We run the program as below and the copy the result to local file system $ hadoop jar $ HADOOP_HOME / share / hadoop / mapreduce / hadoop-mapreduce-examples-2.3..jar wordcount / user / data / intest. txt / test / output Here the Third argument is jar file which contains class file (wordcount.class) for wordcount program Install Hadoop. The most trivial way to get Hadoop up and running is to start a Docker container with Apache's Hadoop 2.6.0 Docker image, based on Ubuntu 14.04. These instructions assume your development machine is also running Ubuntu 14.04. Skip to the next section if your Hadoop is already set up, or you would like to configure it manually

Our program will mimick the WordCount, i.e. it reads text files and counts how often words occur. The input is text files and the output is text files, each line of which contains a word and the count of how often it occured, separated by a tab. Running Hadoop On Ubuntu Linux. <output directory> is the directory where the output of the Hadoop MapReduce WordCount program is going to be stored. This will start the execution of MapReduce job. Now we have run the Map Reduce job successfully. Let us now check the result. Step 13. Browse the Hadoop MapReduce Word Count Project Output * Install and run a program using Hadoop! This course is for those new to data science. No prior programming experience is needed, although the ability to install applications and utilize a virtual machine is necessary to complete the hands-on assignments Right click the package you created in step 2, and select New > Kotlin File/Class Name the file WordCount.kt. Here's the Kotlin code equivalent of the Java example that should go inside WordCount.kt. Notice that the class names are the same and the functions/properties of the classes are basically the same as well The first MapReduce program most of the people write after installing Hadoop is invariably the word count MapReduce program. That's what this post shows, detailed steps for writing word count MapReduce program in Java, IDE used is Eclipse
