> Zookeepers nodes are not removed
> --------------------------------
>
> Key: TWILL-131
> URL: https://issues.apache.org/jira/browse/TWILL-131
> Project: Apache Twill
> Issue Type: Bug
> Components: discovery, zookeeper
> Affects Versions: 0.5.0-incubating
> Reporter: Colin B.
> Assignee: Alvin Wang
> Fix For: 0.7.0-incubating
>
>
> 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.
