Prabhu Joseph commented on YARN-7982:
-------------------------------------
Thanks [~abmodi] for reviewing.
1. The {{TimelineReaderContext.getUserId()}} does not present if user does not
set Query Parameter {{userId}} in
Rest API {{TimelineReaderWebServices#getEntityTypes}}. The {{userId}} is
fetched and set in the context at
{{EntityTypes#readEntityTypes}} -> {{augmentparams}} from AppToFlowTable.
Reusing the same context so that the
{{TimelineReaderWebServices#getEntityTypes}} will have userid to check access.
2. In {{FileSystemTimelineReadeImpl}}, {{context.getUserId}} is null if user
does not set Query Parameter {{userId}}.
Setting it from the Flow Run Path.
