----------------------------------
That's exactly what I was looking for. I'll mark this issue as resolved.
Thanks!

> application data

> Key: TWILL-104
> URL: https://issues.apache.org/jira/browse/TWILL-104
> Project: Apache Twill
> Issue Type: Improvement
> Components: yarn
> Affects Versions: 0.3.0-incubating, 0.4.0-incubating, 0.5.0-incubating
> Reporter: Mike Walch
>
> In YarnTwillRunnerService.watchLiveApps(), all child nodes of the Zookeeper
> root are considered Twill applications and are watched for changes. On a
> cluster, other non-twill applications could be storing data in the same
> zookeeper. It would be better if "/twill" was used for the root or if users
> could specify another root path in Zookeeper for Twill data. Watching the
> Zookeeper nodes of non-twill applications could be causing the delay seen in
> TWILL-103.
