Rohith Sharma K S commented on YARN-5561: ----------------------------------------- bq. One concern I have is, shall we expose the semantics of "containers" and "appattempts" in timeline reader API level? Sorry could not understand this fully. I assume that you are asking to create another web service with different path like AHSWebService which internally redirect the calls to getEntites in TimeLineReaderWebApp. So there will be two @Path i.e */ws/v2/timeline* and */ws/v2/applicationhistory* exposed in ATSv2. Is it ? bq. Similar to the past AHS APIs, maybe we'd like to abstract a separate layer of APIs for YARN to read data from timeline service? Sorry I could not get it. > [Atsv2] : Support for ability to retrieve apps/app-attempt/containers and > entities via REST > ------------------------------------------------------------------------------------------- > > Key: YARN-5561 > URL: https://issues.apache.org/jira/browse/YARN-5561 > Project: Hadoop YARN > Issue Type: Sub-task > Components: timelinereader > Reporter: Rohith Sharma K S > Assignee: Rohith Sharma K S > Attachments: YARN-5561.patch, YARN-5561.v0.patch > > > ATSv2 model lacks retrieval of {{list-of-all-apps}}, > {{list-of-all-app-attempts}} and {{list-of-all-containers-per-attempt}} via > REST API's.
