Would I use something like this to get to those VM arguments? val runtimeMxBean = ManagementFactory.getRuntimeMXBean val args = runtimeMxBean.getInputArguments val conf = Conf(args) etc.

Each java process for each of the executors has some environment variables that you can used, for example: > CONTAINER_ID=container_1503994094228_0054_01_000013 The executor id gets passed as an argument to the process: > /usr/lib/jvm/java-1.8.0/bin/java … --driver-url > spark://CoarseGrainedScheduler@:38151 --executor-id 3 --hostname ip-1… And it gets printed out in the container log: > 17/08/29 13:02:00 INFO Executor: Starting executor ID 3 on host … On Mon, Aug 28, 2017 at 5:41 PM, Mikhailau, Alex <alex.mikhai...@mlb.com<mailto:alex.mikhai...@mlb.com>> wrote: Thanks, Vadim. The issue is not access to logs. I am able to view them. I have cloudwatch logs agent push logs to elasticsearch and then into Kibana using json-event-layout for log4j output. I would like to also log applicationId, executorId, etc in those log statements for clarity. Is there an MDC way with spark or something other than to achieve this?

When you create a EMR cluster you can specify a S3 path where logs will be saved after cluster, something like this: s3://bucket/j-18ASDKLJLAKSD/containers/application_1494074597524_0001/container_1494074597524_0001_01_000001/stderr.gz http://docs.aws.amazon.com/emr/latest/ManagementGuide/emr-manage-view-web-log-files.html On Mon, Aug 28, 2017 at 4:43 PM, Mikhailau, Alex <alex.mikhai...@mlb.com<mailto:alex.mikhai...@mlb.com>> wrote: Does anyone have a working solution for logging YARN application id, YARN container hostname, Executor ID and YARN attempt for jobs running on Spark EMR 5.7.0 in log statements?
