Amazing discoveries by an aging storage professional catching up with BigData
In this post I will explain how to run the Hadoop Streaming utility on a Hadoop Cluster in Pseudo-Distributed Mode. Hadoop Streaming uses executables or scripts to create a MapReduce job and submits the job to a Hadoop cluster. In an earlier post I have explained how to run Hadoop Streaming in Standalone (Local) Mode. …
In this post I will explain how to configure Apache Hadoop in Pseudo-Distributed Mode. In an earlier post I have explained how to install Apache Hadoop in Local (Standalone) Mode. Now I will apply the required configuration changes to turn that cluster into Pseudo-Distributed Mode. Step 1 – Install Apache Hadoop in Local (Standalone) Mode: …
In the last post (BigData Investigation 5 – MapReduce with Python and Hadoop Streaming) we came across different Hadoop cluster modes. This post explains the three supported Hadoop cluster modes. A Hadoop cluster can be configured in one of three modes. Fully-Distributed Mode allows to configure Hadoop clusters ranging from a few nodes to thousands …
