In fact, see the official Hadoop document has been able to easily configure the distributed framework to run the environment, but since the write a little bit more, at the same time there are some details to note that the fact that these details will let people grope for half a day. Hadoop can run stand-alone, but also can configure the cluster run, single run will not need to say more, just follow the demo running instructions directly to execute the command. The main point here is to talk about the process of running the cluster configuration. Environment 7 ordinary machines, operating systems are Linux. Memory and CPU will not say, anyway had ...

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 ...

With the start of Apache Hadoop, the primary issue facing the growth of cloud customers is how to choose the right hardware for their new Hadoop cluster. Although Hadoop is designed to run on industry-standard hardware, it is as easy to come up with an ideal cluster configuration that does not want to provide a list of hardware specifications. Choosing the hardware to provide the best balance of performance and economy for a given load is the need to test and verify its effectiveness. (For example, IO dense ...

Hadoop is a distributed computing open source framework for the Apache open source organization that has been applied to many large web sites, such as Amazon, Facebook and Yahoo. For me, one of the most recent usage points is the log analysis of the service integration platform. The service integration platform's log volume will be very large, and this also coincides with the application of distributed computing scenarios (log analysis and indexing is the two major scenarios). Today we will actually build a Hadoop 2.2.0 version, the actual combat environment for the current mainstream server operating system C ...
