-------------------------------------
Summary: Occasional concurrent modification exception during BP
provision of large clusters
Key: AMBARI-12009
URL: https://issues.apache.org/jira/browse/AMBARI-12009
Project: Ambari
Issue Type: Bug
Components: blueprints
Affects Versions: 2.1.0
Reporter: John Speidel
Assignee: John Speidel
Fix For: 2.1.0
When provisioning large clusters via a blueprint, a concurrent modification
exception may occur occasionally because the topology manager task executor
thread is attempting to create a copy of a collection that is being modified in
another thread. Although this exception is caught in the BP provisioning code
and retried successfully it is an easy fix and should be fixed in 2.1 to avoid
retries which slows down cluster provisioning.
