10/18/2021, 4:38 PM@early-lamp-41924, when I provide corpGroup/corpUser as the entityType it works fine . So unless there is a particular rule that I am missing, I am not sure how to proceed

10/18/2021, 4:52 PMIs squad a new entity you are creating? This field should indicate what type of entity this urn is referring to. From here, seems like it should point to corpGroup entities
early-lamp-41924
10/18/2021, 4:54 PMso shouldn’t be specific to specific value of entity

10/18/2021, 8:01 PMYes, squad is a new entity that I am creating.

early-lamp-41924
10/18/2021, 8:15 PMNot a type right?
early-lamp-41924
10/18/2021, 8:15 PMYeah annotations should not be entity specific but rather denote overall relationships between entity types. So here you should add corpGroup

10/19/2021, 2:45 PMI think you and Pratick are using the term entity differently. We defined a new set of models (SquadKey.pdl, SquadInfo.pdl, SquadSnapshot.pdl) to represent the Squad entityType. In the past we had been using the term Entity to refer to both [an instance of data] and [data types], which was confusing to be sure. Given that, the problem is in fact that we want to use our entityType, not the built-in CorpGroup type, because our model is enough different from corpGroup that we wanted something different.

10/19/2021, 3:27 PMGot it! Understood now. Are you using the config file based entity registration? Just realized by reading through that task throwing error that it currently only supports the old way of registering a new entity. The old way we are trying to deprecate is to add to the Snapshot.pdl https://github.com/linkedin/datahub/blob/master/metadata-models/src/main/pegasus/com/linkedin/metadata/snapshot/Snapshot.pdl This means creating a snapshot of the new entity type. We will get a fix out for this task asap, but if you want to try it out at the current state, can you try following this old way?
