Roshan Naik commented on FLUME-2127:
------------------------------------
It is not clear to me how the problem would go away. the service would still
need a way to start/stop flume java process cleanly. also does not seem
feasible to solve the unit testing issues.
> JMX shutdown command for Flume

> There is a problem when the "integration tests" are attempting to stop flume
> on Windows using Process.destroy(). This does a brute force kill of the top
> level shell (running the startup script) which then leaves a child java
> process (i.e flume agent) running.
> The brute force kill does not allow the shell to terminate the child java
> process. Maven somehow notices that child processes are running and waits
> indefinitely for them to terminate... causing a hang.
> Suggestion is to implement a shutdown command support using JMX. This gives
> the integration tests a graceful mechanism to terminate flume. Also in
> production use cases this mechanism can be secured with authentication etc.
