Previously we set up a Scala application in order to execute a simple word count on hadoop. What comes next is uploading our application to HDInsight. So we shall proceed in creating a Hadoop cluster on HDInsight.               Then we will create the hadoop cluster. As you can see we specify the admin console ...

Hadoop is a great technology built with java. Today we will use Scala to implement a simple map reduce job and then run it using HDInsight. We shall add the assembly plugin on our assembly.sbt addSbtPlugin("com.eed3si9n" % "sbt-assembly" % "0.14.3") Then we will add the Hadoop core dependency on our build.sbt file. Also will we apply some configuration in the ...

Unfortunately all my attempts to upload any files from my local file system to HDFS were being met with the following exception: java.io.IOException: File /user/markneedham/book2.txt ...

Intro This project allows running HDFS on Mesos. You should be familiar with HDFS and Mesos basics: http://mesos.apache.org/documentation/latest/ https://hadoop.apache.org/docs/r2.7.2/hdfs_design.html         Project requires: Mesos 0.23.0+ JDK 1.7.x Hadoop 1.2.x or 2.7.x Mesos in Vagrant Project includes vagrant environment, that allows to run Mesos cluster locally. If you are going to use external Mesos cluster, you can skip this section. 1. ...

In some circles today there is a sort of ‘Hadoop vs. RDBMS’ debate ongoing. Often the discussion casts Hadoop as the obvious heir apparent in the data processing world, with RDBMS cast as your father’s Oldsmobile. This debate is somewhat misdirected and the discussion could lead organizations away from the strategy they really should be following, namely a strategy of ...

Sqoop is a popular data transfer tool for Hadoop. Sqoop allows easy import and export of data from structured data stores like relational databases, enterprise data warehouses, and NoSQL datastores. Sqoop also integrates with Hadoop-based systems such as Hive, HBase, and Oozie. In this blog post, I will cover the different options available for managing passwords in Sqoop. Sqoop is ...

Apache Hadoop is an open-source software framework written in Java for distributed storage and distributed processing of very large data sets on computer clusters built from commodity hardware. All the modules in Hadoop are designed with a fundamental assumption that hardware failures are common and should be automatically ...
