Ryan Blue updated SPARK-13688: ------------------------------ Affects Version/s: 1.6.0 > Add option to use dynamic allocation even if spark.executor.instances is set. > ----------------------------------------------------------------------------- > > Key: SPARK-13688 > URL: https://issues.apache.org/jira/browse/SPARK-13688 > Project: Spark > Issue Type: Bug > Components: YARN > Affects Versions: 1.6.0 > Reporter: Ryan Blue > > When both spark.dynamicAllocation.enabled and spark.executor.instances are > set, dynamic resource allocation is disabled (see SPARK-9092). This is a > reasonable default, but I think there should be a configuration property to > override it because it isn't obvious to users that dynamic allocation and > number of executors are mutually exclusive. We see users setting > --num-executors because that looks like what they want: a way to get more > executors. > I propose adding a new boolean property, > spark.dynamicAllocation.overrideNumExecutors, that makes dynamic allocation > the default when both are set and uses --num-executors as the minimum number > of executors. -- 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
