-------------------------------------
Summary: Avoid erroneous 'Could not cancel' warning produced by
cache tasks
Key: CURATOR-98
URL: https://issues.apache.org/jira/browse/CURATOR-98
Project: Apache Curator
Issue Type: Bug
Components: Client
Affects Versions: 2.4.1
Reporter: Joe Littlejohn
Pull request:
https://github.com/apache/curator/pull/3
When closing providers, we regularly see an erroneous warning related to a
failure to cancel cache tasks.
This change applies some more defensive checks before attempting to cancel
tasks, ensuring that the cancel operation is only attempted if the future has
not completed.
