-----------------------------------

             Summary: Improve TimelineMetricsCache eviction/flush logic using a cache library
                 Key: AMBARI-16821
                 URL: https://issues.apache.org/jira/browse/AMBARI-16821
             Project: Ambari
          Issue Type: Bug
          Components: ambari-metrics
    Affects Versions: 2.2.2
            Reporter: Dmytro Sen
            Assignee: Dmytro Sen
             Fix For: 2.4.0


The TimelineMetricsCache implementation in the metrics sink side is currently a ConcurrentSkipListMap.
It is better to use pre built cache libraries like Guava that offer more support.
