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.
