Project: Ambari
Issue Type: Bug
Components: ambari-server
Affects Versions: 2.0.0
Reporter: Myroslav Papirkovskyi
Assignee: Myroslav Papirkovskyi

Occurred once after upgrade. REST endpoints for agents became inaccessible and
agents were unable to send heartbeats.
Research has shown that all jetty worker threads were in infinite loop while
reading from HashMap which was not threadsafe.
