This recipe describes how to add a third FortiGate to an already established FGCP cluster (the cluster from High Availability with FGCP) and configure active-active HA.

What we want to does in this tutorial, I'll describe the required tournaments for setting up a multi-node Hadoop cluster using the Hadoop Distributed File System (HDFS) on Ubuntu Linux. Are you looking f ...

Introduction to Namenode in Hadoop is like the heart of a human being, and it's important not to stop working. In the HADOOP1 era, there was only one namenode. If the Namenode data is missing or does not work, the entire cluster cannot be recovered. This is a single point in the Hadoop1 and a hadoop1 unreliable performance, as shown in Figure 1. 　　HADOOP2 solved the problem. The high reliability of HDFs in hadoop2.2.0 means that you can start 2 name ...

Projects in the private cloud using CDH (Cloudera Distribution Including Apache Hadoop) Hadoop cluster for big data computing. As a big fan of Microsoft, deploying CDH into Windows Azure VMs is my inevitable choice. Because there are multiple open source services in the CDH, there are many ports that virtual machines need to open. Windows Azure virtual machine's network is securely isolated, so in Windows Azu ...
