Eron Wright commented on SPARK-4940: ------------------------------------- Another benefit of maximizing the # of allocated executors is improved data locality, assuming that HDFS is running on most/all slaves. In other words, executor allocation isn't data-aware, but Spark task allocation is. > Support more evenly distributing cores for Mesos mode > ----------------------------------------------------- > > Key: SPARK-4940 > URL: https://issues.apache.org/jira/browse/SPARK-4940 > Project: Spark > Issue Type: Improvement > Components: Mesos > Reporter: Timothy Chen > Attachments: mesos-config-difference-3nodes-vs-2nodes.png > > > Currently in Coarse grain mode the spark scheduler simply takes all the > resources it can on each node, but can cause uneven distribution based on > resources available on each slave. -- 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
