---------------------------------
Summary: Timeline entity uniqueness
Key: YARN-3588
URL: https://issues.apache.org/jira/browse/YARN-3588
Project: Hadoop YARN
Issue Type: Bug
Reporter: Zhijie Shen
Assignee: Zhijie Shen
In YARN-3051, we have some discussion about how to uniquely identify an entity.
Sangjin and some other folks propose to only uniquely identify an entity by
<type, id> in the scope of a single app. This is different from entity
uniqueness in ATSv1, where <type, id> can globally identify an entity. This is
going to affect the way of fetching a single entity, and raise the
compatibility issue. Let's continue our discussion here to unblock YARN-3051.
