---------------------------------------
Summary: Deleting host from cluster leaves Ambari in inconsistent
state (intermittently)
Key: AMBARI-21168
URL: https://issues.apache.org/jira/browse/AMBARI-21168
Project: Ambari
Issue Type: Bug
Components: ambari-server
Reporter: Sandor Magyari
Assignee: Sandor Magyari
Priority: Critical
Fix For: 2.5.2
When deleting several components and hosts from Ambari under some circumstances
it could happen that a serviceComponentHost is deleted from cache but it's
still present in the DB. Since there are no DB errors in logs, probably it gets
reinserted by a concurrent merge. For ex. HeatbeatProcessor may update the
state meanwhile deleting components, which could result in such situation.
