Karthik Kambatla reassigned YARN-56: ------------------------------------ Assignee: Karthik Kambatla > Handle container requests that request more resources than currently > available in the cluster > --------------------------------------------------------------------------------------------- > > Key: YARN-56 > URL: https://issues.apache.org/jira/browse/YARN-56 > Project: Hadoop YARN > Issue Type: Improvement > Components: resourcemanager > Affects Versions: 2.0.2-alpha, 0.23.3 > Reporter: Hitesh Shah > Assignee: Karthik Kambatla > > In heterogenous clusters, a simple check at the scheduler to check if the > allocation request is within the max allocatable range is not enough. > If there are large nodes in the cluster which are not available, there may be > situations where some allocation requests will never be fulfilled. Need an > approach to decide when to invalidate such requests. For application > submissions, there will need to be a feedback loop for applications that > could not be launched. For running AMs, AllocationResponse may need to > augmented with information for invalidated/cancelled container requests. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
