I. Introduction of FlumeFlume is a distributed, reliable, and highly available mass-log aggregation system that enables the customization of various data senders in the system for data collection, while Flume provides the ability to simply process the data and write to various data-receiving parties (customizable).Design goal:(1) ReliabilityWhen a node fails, the log can be transmitted to other nodes without loss.

Flume can collect files,socket packets and other forms of source data, but also can export the collected data to HDFS,hbase , Many external storage systems such as Hive,

To improve performance, we moved this step into the channel, so we developed the Nullchannel.2.6 Increase KafkasinkTo support the provision of real-time data streams to storm, we have added Kafkasink to write real-time data streams to Kafka. Its basic logic is as follows:public class Kafkasink extends Abstractsink implements configurable {private String zkconnect; Private Integer zktimeout; Private Integer batchsize; P

FileChannel event = Filetransaction.take (); if (event = = null) { Takefrommemchannel.set (TRUE); Puttomemchannel.set (TRUE); } } return event; Copy the Code 2.5 Added Nullchannel Flume provides nullsink, which can discard unwanted logs directly through Nullsink, without storing them. However, source needs to store events in the channel first, and nullsink the events out and throws them away. To improve performance, we moved this step into the

From Bin/flume this shell script can see Flume starting from the Org.apache.flume.node.Application class, which is where the main function of Flume is. The main method first resolves the shell command, throwing an exception if the specified configuration file does not exist. According to the command contains "no-reload-conf" parameters, decide which way to load t

than most messaging systems, making Kafka a good solution for large-scale messaging applications. The messaging system generally has relatively low throughput, but requires a smaller end-to-end delay and a taste of the robust durability protection that is dependent on Kafka. In this field, Kafka is comparable to traditional messaging systems such as ACTIVEMR or
