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

             Summary: ATS does not reflect changes to uploaded TimelineEntity
                 Key: YARN-2445
                 URL: https://issues.apache.org/jira/browse/YARN-2445
             Project: Hadoop YARN
          Issue Type: Bug
          Components: timelineserver
            Reporter: Marcelo Vanzin
            Priority: Minor
         Attachments: ats2.java

If you make a change to the TimelineEntity and send it to the ATS, that change is not reflected in the stored data.

For example, in the attached code, an existing primary filter is removed and a new one is added. When you retrieve the entity from the ATS, it only contains the old value:

{noformat}
{"entities":[{"events":[],"entitytype":"test","entity":"testid-ad5380c0-090e-4982-8da8-21676fe4e9f4","starttime":1408746026958,"relatedentities":{},"primaryfilters":{"oldprop":["val"]},"otherinfo":{}}]}
{noformat}

Perhaps this is what the design wanted, but from an API user standpoint, it's really confusing, since to upload events I have to upload the entity itself, and the changes are not reflected.
