A guide to building a video game with Python. What you’ll get from it: This course provides hands-on Hadoop with MapReduce, HDFS, Spark, Flink, Hive, HBase, MongoDB, Cassandra, Kafka, etc. Hadoop fs -ls /sales/data Related Online Courses Hadoop fs -put /Users/raghunathan.bakkianathan/Work/testData.csv /sales/data Hadoop Health: Yarn: Running Basic HDFS Command hadoop fs -mkdir -p /sales/data Starting nodemanagers Use JPS command to check if all name node, Data node, resource manager is started successfully Run start-all.sh in the sbin folder cd $HADOOP_HOME/sbin/start-all.sh Starting namenodes on Note: Open terminal and Initialize Hadoop cluster by formatting HDFS directory Final Step # export JAVA_HOME export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_141.jdk/Contents/Home hdfs format Open $ HADOOP_HOME/etc/hadoop/hadoop-env.sh file in terminal and add below properties $HADOOP_MAPRED_HOME/share/hadoop/mapreduce/*:$HADOOP_MAPRED_HOME/share/hadoop/mapreduce/lib/* Open $HADOOP_HOME/etc/hadoop/mapred-site.xml file in termial and add below properties. whitelistJAVA_HOME,HADOOP_COMMON_HOME,HADOOP_HDFS_HOME,HADOOP_CONF_DIR,CLASSPATH_PREPEND_DISTCACHE,HADOOP_YARN_HOME,HADOOP_MAPRED_HOME Open $HADOOP_HOME/etc/hadoop/yarn-site.xml file and add below properties Open $HADOOP_HOME/etc/hadoop/Hdfs-site.xml file in terminal and add below properties Open $HADOOP_HOME/etc/hadoop/Core-site.xml in terminal and add below properties Hadoop Installed Path /usr/local/Cellar/hadoop/3.3.0/libexec/etc/hadoop Core-site.xml Get the configuration variables in ~/.bash_profile file in $HOME directory # JAVA env variablesexport JAVA_HOME="/Library/Java/JavaVirtualMachines/adoptopenjdk-8.jdk/Contents/Home"Įxport HADOOP_HOME="/usr/local/Cellar/hadoop/3.3.0/libexec"Įxport HADOOP_CONF_DIR=$HADOOP_HOME/etc/hadoopĮxport HADOOP_COMMON_LIB_NATIVE_DIR=$HADOOP_HOME/lib/nativeĮxport HADOOP_OPTS="=$HADOOP_HOME/lib"Įxport HADOOP_CLASSPATH=$/lib/tools.jarĮxport HIVE_HOME=/usr/local/Cellar/hive/3.1.2_3/libexecĮxport PATH=$PATH:/usr/local/mysql-8.0.12-macos10.13-x86_64/bin Please make the changes with the below configuration details to the following files under $HADOOP_HOME/etc/hadoop/ to set HDFS. This command was run using /usr/local/Cellar/hadoop/3.3.0/libexec/share/hadoop/common/hadoop-common-3.3.0.jar Hadoop configuration If there is an information receipt, the installation is successful. 
In our case Hadoop 3.3.0 at the time of writing this article.Īfter the installation is complete, we enter “ hadoop version” to view the version.

Note: In recent versions, the mac should have built-in java, but it is possible that the version will be lower, and the lower version will affect the installation of Hadoop. OpenJDK 64-Bit Server VM (AdoptOpenJDK)(build 25.252-b09, mixed mode) OpenJDK Runtime Environment (AdoptOpenJDK)(build 1.8.0_252-b09)
Then enter the java -version in the terminal, you can see the Java version. Then, execute source ~/.bash_profile in the terminal to make the configuration file effective. Place the following statement in the blank line export JAVA_HOME=”/Library/Java/JavaVirtualMachines/ jdk version.jdk/Contents/Home”. Enter vim ~/.bash_profile in the terminal to configure the Java path. JDK is installed in the directory /Library/Java/JavaVirtualMachines. After the installation is complete, Configure the environment variables of JAVA. 
If no version is returned then go for the official website to install it
Open the terminal and enter java -version to check the current Java version. The installation of Hadoop is divided into these steps: #MAC INSTALL JAVA RUNTIME THROUGH HOMEBREW HOW TO#
In this article, I will take you through step by step on how to easily install Hadoop 3.3.0 on a mac OS – Big Sur (version 11.2.1) with HomeBrew for a single node cluster in pseudo-distributed mode.
