When it comes to Hadoop has to say cloud computing, I am here to say the concept of cloud computing, in fact, Baidu Encyclopedia, I just copy over, so that my Hadoop blog content does not appear so monotonous, bone feeling. 　　Cloud computing has been particularly hot this year, and I'm a beginner, writing down some of the experiences and processes I've taught myself about Hadoop. Cloud computing (cloud computing) is an increase, use, and delivery model of internet-based related services, often involving the provision of dynamically scalable and often virtualized resources over the Internet. The Cloud is ...

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 ...

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 ...
