2017-09-06 Zhu Big Data and cloud computing technologies Any production system will produce a large number of logs during operation, and the log often hides a lot of valuable information. These logs are stored for a period of time and are cleaned up before the method is parsed. With the development of technology and the improvement of analytical ability, the value of log is re-valued. Before you analyze these logs, you need to collect the logs that are scattered across production systems. Thi

What is a. Flume?Flume is a distributed, reliable system. It can efficiently collect, consolidate, and move large amounts of data from different sources to data center storage.Flume is a top-level project under Apache. Flume not only collects consolidated log data, because the data source can be customized, flume can b

This method requires only a small amount of configuration to complete the data Extraction task, but the disadvantage is also obvious, that is the real-time nature.
