JavaScript and the Browser In HTML, an ampersand (&) character followed by a word and a semicolon (;) is called an entity, and will be replaced by the character it encodes. A script tag must always be closed with </script>, even if it refers to a script file and doesn’t contain any code. If you forget this, the rest of the page will be interpreted as part of the script.
Purpose This document describes how to set up and configure a 3-nodes Hadoop 1.x Distributed File System (HDFS) cluster.
Prerequisites 3 CentOS 6.x VMs In the following examples I have three nodes: node1: 192.168.0.11 node2: 192.168.0.12 node3: 192.168.0.13 The finally setup will be: NameNode: node1 Secondary NN: node2 DataNode: node2 node3 Steps Followings steps are for: CentOS 6.7, Hadoop-1.2.1
Installing Software (3 nodes) Install Java 7 1 2 3 4 5 tar -xzvf jdk-7u79-linux-x64.
The Document Object Model scans a document for text nodes containing a given string and returns true when it has found one 1 2 3 4 5 6 7 8 9 10 11 12 13 function talksAbout(node, string) { if (node.nodeType == document.ELEMENT_NODE) { for (var i = 0; i < node.childNodes.length; i++) { if (talksAbout(node.childNodes[i], string)) return true; } return false; } else if (node.nodeType == document.
