combined freely. The combination method is very flexible based on the configuration file set by the user. For example: Channel can put events in memory, or can be persisted to the local hard drive. Sink can write the log to HDFs, HBase, or even another source, and so on. Flume supports users to build multilevel streams, which means that multiple agents can work together and support Fan-in, fan-out, contextual Routing, Backup Routes, which is also NB.

So the stability of OG's exercise is dependent on zookeeper.3, NG version of the user requirements greatly reduced: installation process In addition to Java without the need to configure complex flume related attributes, also do not need to build zookeeper cluster, installation process almost 0 workload.Some people are puzzled, how suddenly came out of a zookeeper thi
