Rohith Sharma K S commented on YARN-6027:
-----------------------------------------

bq.  could not finally decipher in the comments above why there are separate 
rows for flow runs of the same flow in the flow activity table? cc Rohith 
Sharma K S? This should not happen. There should be exactly one row for a flow 
on a given day.
Right, given a day, only one entry for flow and multiple flowRuns can be there. 
If same flow runs daily lets say 7 days, then */flows* gives 7 flows which are 
duplicated. So, I was thinking, by default can't we give current day flows only?

> In YARN-5585 , fromId is supported for retrieving entities. We need similar 
> filter for flows/flowRun apps and flow run and flow as well. 
> Along with supporting fromId, this JIRA should also discuss following points
> * Should we throw an exception for entities/entity retrieval if duplicates 
> found?
> * TimelieEntity :
> ** Should equals method also check for idPrefix?
> ** Does idPrefix is part of identifiers?
