Patrick Wendell updated SPARK-2673: ----------------------------------- Component/s: Spark Core > Improve Spark so that we can attach Debugger to Executors easily > ---------------------------------------------------------------- > > Key: SPARK-2673 > URL: https://issues.apache.org/jira/browse/SPARK-2673 > Project: Spark > Issue Type: Improvement > Components: Spark Core > Reporter: Kousuke Saruta > > In current implementation, we are difficult to attach debugger to each > Executor in the cluster. > There are reasons as follows. > 1) It's difficult for Executors running on the same machine to open debug > port because we can only pass same JVM options to all executors. > 2) Even if we can open unique debug port to each Executors running on the > same machine, it's a bother to check debug port of each executor. > To solve those problem, I think following 2 improvement is needed. > 1) Enable executor to open unique debug port on a machine. > 2) Expand WebUI to be able to show debug ports opening in each executor. -- This message was sent by Atlassian JIRA (v6.2#6252)
