Karthik Kambatla commented on YARN-1098: ---------------------------------------- bq. Unrelated. Why are the secret manager not services themselves? If they were we wouldnt have to handle them separately in start and stop. Created YARN-1172 to address this. > Separate out RM services into "Always On" and "Active" > ------------------------------------------------------ > > Key: YARN-1098 > URL: https://issues.apache.org/jira/browse/YARN-1098 > Project: Hadoop YARN > Issue Type: Sub-task > Components: resourcemanager > Affects Versions: 2.1.0-beta > Reporter: Karthik Kambatla > Assignee: Karthik Kambatla > Labels: ha > Attachments: yarn-1098-1.patch, yarn-1098-2.patch, yarn-1098-3.patch, > yarn-1098-4.patch, yarn-1098-5.patch, yarn-1098-approach.patch, > yarn-1098-approach.patch > > > From discussion on YARN-1027, it makes sense to separate out services that > are stateful and stateless. The stateless services can run perennially > irrespective of whether the RM is in Active/Standby state, while the stateful > services need to be started on transitionToActive() and completely shutdown > on transitionToStandby(). > The external-facing stateless services should respond to the client/AM/NM > requests depending on whether the RM is Active/Standby. -- This message is automatically generated by JIRA.
