In addition, when configuration data changes, zookeeper can notify the flume master node.

Cloudera cdh4 has three installation methods: 1. Automatic Installation through cloudera Manager (only 64-bit Linux operating systems are supported ); 2. Use the yum command to manually install the package; 3. Manually install the tarball package; I personally recommend that you try either method 1 or 2. You should first have a clear understanding of the hadoop a
