Earlier, we were already running Hadoop on a single machine, but we know that Hadoop supports distributed, and its advantage is that it is distributed, so let's take a look at the environment. Here we use a strategy to simulate the environment. We use three Ubuntu machines, one for the master and the other two for the slaver. At the same time, this host, we use the first chapter to build a good environment. We use the steps similar to the first chapter to operate: 1, the operating environment to take ...

In Serengeti, there are two most important and most critical functions: one is virtual machine management and the other is cluster software installation and configuration management. The virtual machine management is to create and manage the required virtual machines for a Hadoop cluster in vCenter. Cluster software installation and configuration management is to install Hadoop related components (including Zookeeper, Hadoop, Hive, Pig, etc.) on the installed virtual machine of the operating system, and update the configuration files like Namenode / Jobtracker / Zookeeper node ...

Ganglia monitoring software is mainly used to monitor the performance of the software, such as: CPU, MEM, hard disk utilization, I/O load, network traffic, etc., through the curve is very easy to see the work of each node, the reasonable adjustment, distribution system resources, improve the overall performance of the system plays an important role. Support browser access, but can not monitor node hardware specifications, ganglia is a distributed monitoring system, there are two Daemon, respectively: Client ganglia monitoring Daemon (Gmond ...

A few weeks ago, I published a blog about Windows Azure cloud services. I'm digging up new things and experimenting with mac,pc and Linux (I prefer Ubuntu). As a fan of PowerShell and command lines for a long time, I've been looking for ways to handle transactions in text mode, as well as the creation and deployment of script sites. There was a whole bunch of ways to access Azure using the command line-more than I thought. There is a JSON based Web API that will let those workers ...

In recent years, Hadoop has received a lot of praise, as well as "moving to the Big data analysis engine". For many people, Hadoop means big data technology. But in fact, open source distributed processing framework may not be able to solve all the big data problems. 　　This requires companies that want to deploy Hadoop to think carefully about when to apply Hadoop and when to apply other products. For example, using Hadoop for large-scale unstructured or semi-structured data can be said to be more than sufficient. But the speed with which it handles small datasets is little known. This limits the ha ...
