Review request for Ambari, Robert Levas, Sumit Mohanty, and Sid Wagle. Bugs: AMBARI-18697 https://issues.apache.org/jira/browse/AMBARI-18697 Repository: ambari Description ------- Got disk full while on ambari server while adding a service, I deleted all stack recommendation output directories and retried, but hit the issue again. AMCImpl: 2317 => kerberosHelper.configureService(cluster, scHost); We are making this call explicitly for every SCH on adding service. For clusters with 1000 nodes, stack_adviser will be called 1000 times with the same request. Diffs ----- ambari-server/src/main/java/org/apache/ambari/server/controller/AmbariManagementControllerImpl.java 09e49ef Diff: https://reviews.apache.org/r/53183/diff/ Testing ------- Unit tests passed Thanks, Dmytro Sen
