Varun Saxena commented on YARN-4074: ------------------------------------ [~sjlee0], yeah it handles null case. I meant we can handle negative values even at the REST layer(as part of YARN-4075) i.e. if the limit is negative I can forward null to storage layer which would mean default limit being applied. > [timeline reader] implement support for querying for flows and flow runs > ------------------------------------------------------------------------ > > Key: YARN-4074 > URL: https://issues.apache.org/jira/browse/YARN-4074 > Project: Hadoop YARN > Issue Type: Sub-task > Components: timelineserver > Affects Versions: YARN-2928 > Reporter: Sangjin Lee > Assignee: Sangjin Lee > Attachments: YARN-4074-YARN-2928.POC.001.patch, > YARN-4074-YARN-2928.POC.002.patch > > > Implement support for querying for flows and flow runs. > We should be able to query for the most recent N flows, etc. > This includes changes to the {{TimelineReader}} API if necessary, as well as > implementation of the API. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
