--------------------------------
Summary: Keep application running even the AM is disconnected from
ZK
Key: TWILL-52
URL: https://issues.apache.org/jira/browse/TWILL-52
Project: Apache Twill
Issue Type: Bug
Components: yarn
Affects Versions: 0.1.0-incubating
Reporter: Terence Yim
Assignee: Terence Yim
Priority: Critical
Currently if the the ZK session of the AM is expired, the YarnTwillController
treats the application stopped and requests YARN to stop the app, which is
undesirable.
To make application resilience to ZK failure, the controller should resort to
polling YARN for the application status until the AM reconnected with ZK.
