To do this, we need to copy generated RSA key (i.e. However we have this single machine, we can try connecting with this same machine by SSH. Once you installed SSH on your machine, you can connect to other machine or allow other machines to connect with this machine. Now, we have installed SSH over Ubuntu machine so we will be able to connect with this machine as well as from this machine remotely. Hadoop uses SSH for accessing another slaves nodes to start and manage all HDFS and MapReduce daemons. SSH (“Secure SHell”) is a protocol for securely accessing one machine from another. We will create hadoop as system group and hduser as system user sudo addgroup sudo adduser -ingroup hadoop hduser To avoid security issues, we recommend to setup new Hadoop user group and user account to deal with all Hadoop related activities.
#HADOOP SETUP INSTALL#
It will install java source in your machine at /usr/lib/jvm/java-8-oracle So, Here you can also try Java 6, 7 instead of Java sudo add-apt-repository sudo apt-get sudo apt-get install oracle-java8-installer Hadoop supports all java version greater than 5 (i.e.
#HADOOP SETUP HOW TO#
If you are looking for instructions over how to setup Hadoop Multinode cluster, visit my next post – PrerequisitesĪpache Hadoop is java framework, we need java installed on our machine to get it run over operating system. To get started with Apache Hadoop install, I recommend that you should have knowledge of basic Linux commands which will be helpful in normal operations while installation task. (You can follow the same blog post for installation over Ubuntu server machine).
This blog post teaches how to install Apache Hadoop 2.6 over Ubuntu machine.
#HADOOP SETUP FULL#
Here, I am trying to covering full fledge Hadoop installation steps for BigData enthusiasts who wish to install Apache Hadoop on their Ubuntu – Linux machine. So, by considering this situation we need to follow slightly different steps than previous version. As Apache Hadoop is the top most contributed Apache project, more and more features are implemented as well as more and more bugs are getting fixed in new coming versions. Since we know it’s the time for parallel computation to tackle large amount of dataset, we will require Apache Hadoop (here the name is derived from Elephant).
