how to set log level of spark executor on YARN(using yarn-cluster mode)

[eric wong]

Hi,

I want to check the DEBUG log of spark executor on YARN(using yarn-cluster
mode), but

1. yarn daemonlog setlevel DEBUG YarnChild.class
2. set log4j.properties in spark/conf folder on client node.

no means above works.

So how could i set the  log level of spark executor* on YARN container to
DEBUG？*

Thanks!
