-----------------------------------------
Summary: Blueprint provisioning code needs more debug logging
Key: AMBARI-12567
URL: https://issues.apache.org/jira/browse/AMBARI-12567
Project: Ambari
Issue Type: Bug
Components: ambari-server
Affects Versions: 2.1.0
Reporter: Robert Nettleton
Assignee: Robert Nettleton
Fix For: 2.1.1
The new Blueprint dynamic provisioning mechanism, added in Ambari 2.1.0, does
not log much useful information when handling the setup of a cluster.
This is particularly problematic in large cluster deployments that use the
predicate syntax in the cluster creation template.
Logging should be added to the TopologyManager and other classes in this area
of Blueprints in order to facilitate simpler debugging of problems,
particularly problems that occur in large-scale, high-concurrency environments.
I'm working on a fix for this, and will be submitting a patch shortly.
