Patrick Wendell updated SPARK-3513: ----------------------------------- Issue Type: Improvement (was: Bug) > 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: Improvement > Components: Spark Core > Reporter: Patrick Wendell > Priority: Minor > > 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
