Subject [jira] [Commented] (YARN-6027) Support fromId for flows API
Date Wed, 11 Jan 2017 09:17:58 GMT

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

Yes, it is doable. We have done POC for the same at one level. The issue we face is aggregated
flows should be limited with constant value nevertheless of user inputed limit. otherwise
if user provides higher limit then possibility of OOM is very high.

> 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?
