Jagadish created SAMZA-1687: ------------------------------- Summary: Prioritize preferred host requests over ANY-HOST requests Key: SAMZA-1687 URL: https://issues.apache.org/jira/browse/SAMZA-1687 Project: Samza Issue Type: Bug Reporter: Jagadish Assignee: Jagadish
Yarn enforces these two checks: 1. ANY_HOST requests should always be made with relax-locality = true 2. A request with relax-locality = false should not be in the same priority as another with relax-locality = true Since the Samza AM makes preferred-host requests with relax-locality = false, it follows that ANY_HOST requests should specify a different priority-level. We can safely set priority of preferred-host requests to be higher than any-host requests since data-locality is critical. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
