Hadoop, a distributed computing open source framework for the Apache open source organization, has been used on many of the largest web sites, such as Amazon, Facebook and Yahoo. For me, a recent point of use is log analysis of service integration platforms. The service integration platform will have a large amount of logs, which is in line with the applicable scenarios for distributed computing (log analysis and indexing are two major application scenarios). Today we come to actually build Hadoop version 2.2.0, the actual combat environment for the current mainstream server operating system C ...
