Sandy Ryza resolved SPARK-4352. ------------------------------- Resolution: Fixed Fix Version/s: 1.5.0 Target Version/s: 1.5.0 > Incorporate locality preferences in dynamic allocation requests > --------------------------------------------------------------- > > Key: SPARK-4352 > URL: https://issues.apache.org/jira/browse/SPARK-4352 > Project: Spark > Issue Type: Improvement > Components: Spark Core, YARN > Affects Versions: 1.2.0 > Reporter: Sandy Ryza > Assignee: Saisai Shao > Priority: Critical > Fix For: 1.5.0 > > Attachments: Supportpreferrednodelocationindynamicallocation.pdf > > > Currently, achieving data locality in Spark is difficult unless an > application takes resources on every node in the cluster. > preferredNodeLocalityData provides a sort of hacky workaround that has been > broken since 1.0. > With dynamic executor allocation, Spark requests executors in response to > demand from the application. When this occurs, it would be useful to look at > the pending tasks and communicate their location preferences to the cluster > resource manager. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
