Description

We have TimelineEntity and some other entities as subclass that inherit from it. However, we only have a single endpoint, which consume TimelineEntity rather than sub-classes and this endpoint will check the incoming request body contains exactly TimelineEntity object. However, the json data which is serialized from sub-class object seems not to be treated as an TimelineEntity object, and won't be deserialized into the corresponding sub-class object which cause deserialization failure as some discussions in YARN-3334 : https://issues.apache.org/jira/browse/YARN-3334?focusedCommentId=14391059&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14391059.
