-------------------------------------
Summary: MesosPathDetector double-counts checkpoint roots
Key: AURORA-1353
URL: https://issues.apache.org/jira/browse/AURORA-1353
Project: Aurora
Issue Type: Bug
Components: Observer
Reporter: brian wickman
This manifests itself in the observer ballooning in resource usage. The
TaskDetector finds two copies of every task because of the 'latest' symlink
being a duplicate of the actual directory, so we get race conditions in
on_active/on_finished inside
src/main/python/apache/thermos/observer/task_observer.py that cause it to hold
onto TaskResourceMonitors which tend to be pretty expensive to run.
