flume installation

The collection of user behavior data is undoubtedly a prerequisite for building a referral system, and the Flume project under the Apache Foundation is tailored for distributed log collection, this is the 1th of the Flume research note, which mainly introduces Flume's basic architecture, The next note will illustrate the deployment and use steps of flume with an

agent. This is how single-hop message delivery semantics in Flume provides end-to-end reliability of the stream.Flume uses transactional approach to ensure the reliable delivery of events. Source and sink encapsulate storage/retrieval in a transaction, placing or providing events by the transaction provided by the channel. This ensures that the set of events can be reliably passed from point to place in the process. In the case of the multi hop proce

collector is the receiving agent sent data, the data sent to the specified target machine. Note: The flume framework's reliance on Hadoop and zookeeper is only on the jar package and does not require that the Hadoop and zookeeper services be started when the flume is started. III.

the basic unit of Flume data transfer* * Flume send data from source to destination as an event* * The envent consists of an optional header and a byte array containing the data, which is opaque to flume, the header holds a collection of Key-value key-value pairs, the key is unique within a set, Headers can also be extended for use in context routing.Flume Trans
