---------------------------------------
Summary: Scale down logic does not execute as intended
Key: STRATOS-614
URL: https://issues.apache.org/jira/browse/STRATOS-614
Project: Stratos
Issue Type: Bug
Components: Autoscaler
Reporter: Imesh Gunaratne
According to a flow test carried out on the latest code base, scale down
functionality does not work as intended.
Scenario:
1. Partition Max Instance Count set to 3
2. Send a sample request load to take scale up action. Autoscaler will spin up
3 instances.
3. Stop the sample request load.
4. Let the service cluster scale down.
5. One instance being terminated but two remains.
As found in the Autoscaler logs Member Stat Context of the terminated member is
not being removed from the Cluster Context. As a result the same member being
selected in each scale down action round.
