------------------------------------
Summary: TwillRunnerService should provide a way to determine that
TwillRunner background load is complete
Key: TWILL-183
URL: https://issues.apache.org/jira/browse/TWILL-183
Project: Apache Twill
Issue Type: Improvement
Components: core
Affects Versions: 0.7.0-incubating
Reporter: Martin Serrano
I see from the source that the TwillRunnerService is locating existing
controllers by querying ZK in the background. Since these run in the
background, there seems to be no way to know when the requests are
complete. Thus, on starting up the service, I can't reliably determine
the complete set of controllers running from previous sessions. Is
there a way to know? Is there a listener I can register?
