Mike Walch created TWILL-104:
--------------------------------
Summary: Enable users to specify a different node than root of
Zookeeper for Twill 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.
