Rohith Sharma K S commented on YARN-9554:
-----------------------------------------
ATSv2 has separate TimelineEntity and TimelineEntities under separate package
i.e org.apache.hadoop.yarn.api.records.timelineservice. And v1 and v2 clients
are different. So, it shouldn't be problem.
> TimelineEntity DAO has java.util.Set interface which JAXB can't handle
