In the distributed system, each machine has the local log that the program runs, sometimes in order to analyze the demand, have to these scattered log summary requirements, I believe many people will choose RSYNC,SCP, but they are not strong in real-time, but also bring the problem of name conflict. The scalability is not satisfactory, not elegant at all.In reality, we are confronted with the need to summarize the Nginx logs of multiple servers on the line in real time.

In a complete large data processing system, in addition to the core of the Hdfs+mapreduce+hive composition Analysis system, data acquisition, result data export, task scheduling and other indispensable auxiliary systems are needed, and these auxiliary tools are There is a convenient open source framework in the Hadoop ecosystem.

Background information Many of the company's platforms generate a large number of logs (typically streaming data, such as the PV of search engines, queries, etc.), which require a specific log system, which in general requires the following characteristics: (1) Construct the bridge of application system and analysis system, and decouple the correlation between them; (2) support the near real-time on-line analysis system and the off-line analysis system similar to Hadoop; (3) with high scalabi
