Zachary Heilbron commented on FLUME-1491:
-----------------------------------------

Please have a look at the latest patch. There were a number of issues 
preventing reload = true from working. This patch fixes them.

I've split the configuration provider into two parts (like the file-based 
provider): one that polls+reconfigures and another that configures just once.

I've verified that both work in a live setting and added a test case for the 
polling version (there already exists a test case for the once-config version).

Also fixed is the flume-ng usage printout and code formatting has been applied.

> Currently, Flume only support file-level dynamic configuration. Another 
> frequent usage in practical environment, we would like to manage 
> configuration with Zookeeper, and modify configuration from Web UI to stored 
> file in Zookeeper. 
> Flume should support this method with Zookeeper watcher.
