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 ...

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 ...
