Summary: Support an AM liveness mechanism that works for both sync/async AM-RM clients Key: YARN-2653 URL: https://issues.apache.org/jira/browse/YARN-2653 Project: Hadoop YARN Issue Type: Improvement Components: client, resourcemanager Reporter: sidharta seethana Priority: Minor Currently, the “heartbeat” mechanism is only supported in the async client ( AMRMClientAsyncImpl ). The reason for this seems to be because liveness monitoring is currently implemented based on periodic (possibly empty) allocation requests - which may return container allocation responses for earlier allocation requests. This mechanism only works for the async client where allocation responses can be queued and is not application to the synchronous/blocking client. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
