Patrick Wendell created SPARK-3513: -------------------------------------- Summary: Provide a utility for running a function once on each executor Key: SPARK-3513 URL: https://issues.apache.org/jira/browse/SPARK-3513 Project: Spark Issue Type: Bug Components: Spark Core Reporter: Patrick Wendell Priority: Minor Fix For: 1.2.0
This is minor, but it would be nice to have a utility where you can pass a function and it will run some arbitrary function once on each each executor and return the result to you (e.g. you could perform a jstack from within the JVM). You could probably hack it together with custom locality preferences, accessing the list of live executors, and mapPartitions. -- 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
