--------------------------------------------
Assignee: Aleksandr Kovalenko
> FE: Switching between different service's configs does not reduce DOM node
> and listeners count
> ----------------------------------------------------------------------------------------------
>
> Key: AMBARI-12554
> URL: https://issues.apache.org/jira/browse/AMBARI-12554
> Project: Ambari
> Issue Type: Bug
> Components: ambari-web
> Affects Versions: 2.1.1
> Reporter: Aleksandr Kovalenko
> Assignee: Aleksandr Kovalenko
> Priority: Critical
> Fix For: 2.1.1
>
>
> Was profiling Ambari-2.1.0 latest build and switching between service's and
> their configuration tabs. The path I took was HDFS (Settings) > HDFS
> (Advanced) > YARN (Settings) > YARN (Advanced) > Hive (Settings) > Hive
> (Advanced), and back to HDFS.
> This route resulted in 122K DOM nodes becoming 219K DOM nodes. Also 159
> listeners became 606 listeners. This was after garbage collection was done.
> It looks like once we go a service's configs page and leave it, we are
> leaving behind DOM nodes and listeners, which keep accumulating and bloating
> the app.
