MapReduce \u2013 Installation:<\/strong><\/b><\/p>\r\n

MapReduce<\/a> works only on Linux operating systems and it comes inbuilt with a Hadoop framework.<\/p>\r\n

In ordered to install the Hadoop your system should have Java. If your system doesn\u2019t have the Java. Firstly install Java on your machine.<\/p>\r\n

Hadoop Installation:<\/strong><\/b><\/p>\r\n

Hadoop must be installed<\/a> on your machine before you are going to install MapReduce. Check your system whether your system having Hadoop or not using code.<\/p>\r\n\r\n\r\n\r\n
$ hadoop version<\/td>\r\n<\/tr>\r\n<\/tbody>\r\n<\/table>\r\n

If your system has the Hadoop then you will get the message.<\/p>\r\n\r\n\r\n\r\n

Hadoop 2.4.1<\/p>\r\n

—<\/p>\r\n

Subversion: https:\/\/svn.apache.org\/repos\/asf\/hadoop\/common\u00a0-r 1529768<\/p>\r\n

Compiled by hortonmu on 2013-10-07T06:28Z<\/p>\r\n

Compiled with protoc 2.5.0<\/p>\r\n

From source with checksum 79e53ce7994d1628b240f09af91e1af4<\/td>\r\n<\/tr>\r\n<\/tbody>\r\n<\/table>\r\n

If Hadoop is not installed then fallow bellow process.<\/p>\r\n

Downloading Hadoop:<\/strong><\/b><\/p>\r\n

Download Hadoop 2.4.1 from Apache Software Foundation and extract its contents using the following commands.<\/p>\r\n\r\n\r\n\r\n

$ su<\/p>\r\n

password:<\/p>\r\n

# cd \/usr\/local<\/p>\r\n

# wget: http:\/\/apache.claz.org\/hadoop\/common\/hadoop-2.4.1\/<\/p>\r\n

hadoop-2.4.1.tar.gz<\/p>\r\n

# tar xzf hadoop-2.4.1.tar.gz<\/p>\r\n

# mv hadoop-2.4.1\/* to hadoop\/<\/p>\r\n

# exit<\/td>\r\n<\/tr>\r\n<\/tbody>\r\n<\/table>\r\n

Installing Hadoop in Pseudo-Distributed mode:<\/strong><\/b><\/p>\r\n

The following steps are used to install Hadoop 2.4.1 in pseudo distributed mode.<\/p>\r\n

Step 1 \u2212 Setting up Hadoop:<\/strong><\/b><\/p>\r\n

You can set Hadoop environment variables by appending the following commands to a ~\/.bashrc file.<\/p>\r\n\r\n\r\n\r\n

export HADOOP_HOME=\/usr\/local\/hadoop<\/p>\r\n

export HADOOP_MAPRED_HOME=$HADOOP_HOME<\/p>\r\n

export HADOOP_COMMON_HOME=$HADOOP_HOME<\/p>\r\n

export HADOOP_HDFS_HOME=$HADOOP_HOME<\/p>\r\n

export YARN_HOME=$HADOOP_HOME<\/p>\r\n

export HADOOP_COMMON_LIB_NATIVE_DIR=$HADOOP_HOME\/lib\/native<\/p>\r\n

export PATH=$PATH:$HADOOP_HOME\/sbin:$HADOOP_HOME\/bin<\/td>\r\n<\/tr>\r\n<\/tbody>\r\n<\/table>\r\n

Apply all the changes to the current running system.<\/p>\r\n\r\n\r\n\r\n
$ source ~\/.bashrc<\/td>\r\n<\/tr>\r\n<\/tbody>\r\n<\/table>\r\n

Step 2 \u2212 Hadoop Configuration:<\/strong><\/b><\/p>\r\n

You can find all the Hadoop configuration files in the location \u201c$HADOOP_HOME\/etc\/hadoop\u201d. You need to make suitable changes in those configuration files according to your Hadoop infrastructure<\/a>.<\/p>\r\n\r\n\r\n\r\n
$ cd $HADOOP_HOME\/etc\/hadoop<\/td>\r\n<\/tr>\r\n<\/tbody>\r\n<\/table>\r\n

In order to develop Hadoop programs using Java, you have to reset the Java environment variables in hadoop-env.sh file by replacing the JAVA_HOME value with the location of Java in your system.<\/p>\r\n\r\n\r\n\r\n
export JAVA_HOME=\/usr\/local\/java<\/td>\r\n<\/tr>\r\n<\/tbody>\r\n<\/table>\r\n

You have to edit the following files to configure Hadoop \u2212<\/p>\r\n

1)\u00a0<\/strong><\/b>core-site.xml<\/p>\r\n

2)<\/strong><\/b>\u00a0hdfs-site.xml<\/p>\r\n

3)<\/strong><\/b>\u00a0yarn-site.xml<\/p>\r\n

4)<\/strong><\/b>\u00a0mapred-site.xml<\/p>\r\n

Core-site.xml:<\/strong><\/b><\/p>\r\n

Core-site.xml<\/a> contains the following information\u2212<\/p>\r\n

    \r\n
  1. <\/b>Port number used for Hadoop instance<\/li>\r\n
  2. <\/b>Memory allocated for the file system<\/li>\r\n<\/ol>\r\n

    iii.<\/strong><\/b>\u00a0Memory limit for storing the data<\/p>\r\n

      \r\n
    1. <\/b>Size of Read\/Write buffers<\/li>\r\n<\/ol>\r\n

      Open the core-site.xml and add the following properties in between the and tags.<\/p>\r\n\r\n\r\n\r\n

      fs.default.name<\/p>\r\n

      hdfs:\/\/localhost:9000<\/td>\r\n<\/tr>\r\n<\/tbody>\r\n<\/table>\r\n

      Hdfs-site.xml:<\/strong><\/b><\/p>\r\n

      Hdfs-site.xml contains the following information \u2212<\/p>\r\n

        \r\n
      1. i)<\/strong><\/b>Value of replication data<\/li>\r\n
      2. ii)\u00a0<\/strong><\/b>The namenode path<\/li>\r\n<\/ol>\r\n

        iii)<\/strong><\/b>\u00a0The datanode path of your local file systems (the place where you want to store the Hadoop infra)<\/p>\r\n

        Let us see the following data.<\/p>\r\n\r\n\r\n\r\n

        dfs.replication (data replication value) = 1<\/p>\r\n

        (In the following path \/hadoop\/ is the user name.<\/p>\r\n

        hadoopinfra\/hdfs\/namenode is the directory created by hdfs file system.)<\/p>\r\n

        namenode path = \/\/home\/hadoop\/hadoopinfra\/hdfs\/namenode<\/p>\r\n

        (hadoopinfra\/hdfs\/datanode is the directory created by hdfs file system.)<\/p>\r\n

        datanode path = \/\/home\/hadoop\/hadoopinfra\/hdfs\/datanode<\/td>\r\n<\/tr>\r\n<\/tbody>\r\n<\/table>\r\n

        Open this file and add the following properties in between the,\u00a0tags.<\/p>\r\n\r\n\r\n\r\n

        dfs.replication<\/p>\r\n

        1<\/p>\r\n

        dfs.name.dir<\/p>\r\n

        file:\/\/\/home\/hadoop\/hadoopinfra\/hdfs\/namenode<\/p>\r\n

        dfs.data.dir<\/p>\r\n

        file:\/\/\/home\/hadoop\/hadoopinfra\/hdfs\/datanode<\/td>\r\n<\/tr>\r\n<\/tbody>\r\n<\/table>\r\n

        Note \u2013<\/strong><\/b>\u00a0According to the above file, all the property values are user-defined and you can make changes according to your Hadoop infrastructure.<\/p>\r\n

        Yarn-site.xml:<\/strong><\/b><\/p>\r\n

        This file is used to configure yarn into Hadoop. Open the yarn-site.xml file and add the following properties in between the, tags.<\/p>\r\n\r\n\r\n\r\n

        yarn.nodemanager.aux-services<\/p>\r\n

        mapreduce_shuffle<\/td>\r\n<\/tr>\r\n<\/tbody>\r\n<\/table>\r\n

        mapred-site.xml:<\/strong><\/b><\/p>\r\n

        This file is used to specify the MapReduce<\/a> framework we are using. By default, Hadoop contains a template of yarn-site.xml. First of all, you need to copy the file from mapred-site.xml.template to mapred-site.xml file using the following command.<\/p>\r\n\r\n\r\n\r\n
        $ cpmapred-site.xml.template mapred-site.xml<\/td>\r\n<\/tr>\r\n<\/tbody>\r\n<\/table>\r\n

        Open mapred-site.xml file and add the following properties in between the, tags.<\/p>\r\n\r\n\r\n\r\n

        mapreduce.framework.name<\/p>\r\n

        yarn<\/td>\r\n<\/tr>\r\n<\/tbody>\r\n<\/table>\r\n

        Verifying Hadoop Installation:<\/strong><\/b><\/p>\r\n

        The below steps are used to verify the Hadoop installation.<\/p>\r\n

        Step 1 \u2212 Name Node Setup:<\/strong><\/b><\/p>\r\n

        Set up the namenode using the command \u201chdfsnamenode -format\u201d as below<\/p>\r\n\r\n\r\n\r\n

        $ cd ~<\/p>\r\n

        $ hdfsnamenode -format<\/td>\r\n<\/tr>\r\n<\/tbody>\r\n<\/table>\r\n

        The expected result is<\/p>\r\n\r\n\r\n\r\n
