------------------------------------------
Summary: UI lags and OutOfMemoryError seen in Ambari server after
dashboard metrics change.
Key: AMBARI-13863
URL: https://issues.apache.org/jira/browse/AMBARI-13863
Project: Ambari
Issue Type: Bug
Components: ambari-metrics
Affects Versions: 2.1.2
Reporter: Aravindan Vijayan
Assignee: Aravindan Vijayan
Priority: Critical
Fix For: 2.1.3
Problem
On the Ambari dashboard page, when different time ranges are randomly chosen,
the metrics charts stop responding and an OutOfMemory is seen in the Ambari
server logs.
Bug
In the AMS cache layer, the logic to update the cache entry map by removing
values outside the given requested time range eventually leads to memory leak.
Fix
Change the logic to explicitly by using the iterator.remove() to remove the
entries instead of using the map.clear() method.
