>             Project: Flume
>          Issue Type: Improvement

> We need a way to take down a node without un-configuring for maintenance 
> (mostly a collector in multi-collector configuration).  The node should be 
> brought back up on restart.  Unconfiguring the node, while an option, 
> requires entering the configuration information again.  Alternatively a 
> command like `exec shutdown physicalnode` will shutdown any logical node on 
> the machine (flush the output, stop input) and optionally terminate the Flume 
> process.  The same may apply to master or an agent (an agent will have to 
> stop accepting or reading the data).  Currently we can just shut down the 
> Java process on machine, which potentially leads to either data loss or data 
> duplication in different modes.
