> When a TwillRunnable is run with the YarnTwillRunnerService, a zookeeper node is created and never removed.
> For example run the example HelloWorld application:
> {code}
> java -cp $CP org.apache.twill.example.yarn.HelloWorld localhost:2181/hello
> {code}
> After the application had run to completion I looked at zookeeper and found:
> {code}
> > ./zkCli.sh ls /hello
> ...
> [HelloWorldRunnable]
> {code}
> However I expected:
> {code}
> > ./zkCli.sh ls /hello
> ...
> []
> {code}
> This becomes an issue when a service creates a large number of TwillApplications with unique names.
