Subject [jira] [Commented] (YARN-6027) Support fromid(offset) filter for /flows API
Date Sat, 18 Feb 2017 05:07:45 GMT

    [ https://issues.apache.org/jira/browse/YARN-6027?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15872992#comment-15872992

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

I am confused with the whole stuff what are we going to achieve. I have 2 basic questions
which need a consensus first.
# Do we want FROM_ID to be added by TimelineReader Server like UID ? Validation is done at
TimelineReaderWebSerice only. 
# Do we want FROM_ID to be added by storage layer? Here, validation will be done at storage
layer 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?
