Quanlong Huang updated IMPALA-7357: ----------------------------------- Target Version: Impala 3.4.0 (was: Impala 3.3.0) > Consider lowering statestore update frequency further or adding jitter to > admission controller > ---------------------------------------------------------------------------------------------- > > Key: IMPALA-7357 > URL: https://issues.apache.org/jira/browse/IMPALA-7357 > Project: IMPALA > Issue Type: Improvement > Components: Backend > Reporter: Tim Armstrong > Priority: Major > Labels: admission-control > > We could consider reducing the update frequency further (maybe just for > coordinators??) and possibly adding some jitter to the admission process to > prevent overadmission when multiple queries are submitted at the same time to > different coordinators. > The problem is that the coordinators independently make admission decisions > before the change in state from previous decisions is propagated to other > coordinators. -- This message was sent by Atlassian JIRA (v7.6.14#76016) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-all-unsubscr...@impala.apache.org For additional commands, e-mail: issues-all-h...@impala.apache.org
