Subject [jira] [Commented] (YARN-6027) Support fromid(offset) filter for /flows API
Date Fri, 17 Feb 2017 09:29:41 GMT

    [ https://issues.apache.org/jira/browse/YARN-6027?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15871517#comment-15871517

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

I would be more leaning towards adding new field FROM_ID rather than re using UID. May be
we need to add FROM_ID field in all the API's so that user can directly pick it up and provide
it as fromId. 
If I look at UID encode/decode implementations, it always expect TimelineReaderContext as
parameter and return type. But all the UID encoding does not happen with row key say UID {{"UID":
"yarn-cluster!application_1484113378396_0001"}}. Instead of using UID, new field always FROM_ID
is always better I feel. I will update v0 patch for proposal, let discuss on v0 patch.

> 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?
