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 ...
