[jira] [Created] (YARN-3836) add equals and hashCode to TimelineEntity and other classes in the data model

Sangjin Lee created YARN-3836:
---------------------------------

             Summary: add equals and hashCode to TimelineEntity and other classes in the data model
                 Key: YARN-3836
                 URL: https://issues.apache.org/jira/browse/YARN-3836
             Project: Hadoop YARN
          Issue Type: Sub-task
          Components: timelineserver
    Affects Versions: YARN-2928
            Reporter: Sangjin Lee


Classes in the data model API (e.g. {{TimelineEntity}}, {{TimelineEntity.Identifer}}, etc.) do not override {{equals()}} or {{hashCode()}}. This can cause problems when these objects are used in a collection such as a {{HashSet}}. We should implement these methods wherever appropriate.
