Hi guys,
I recently ran spark on yarn and found spark didn't set any log4j properties
file in configuration or code. And the log4j logs was writing into stderr
file under ${yarn.nodemanager.log-dirs}/application_${appid}.
I wanna know which side(spark or hadoop) controll the appender? Have found
that related disscussion here:
http://apache-spark-user-list.1001560.n3.nabble.com/Spark-logging-strategy-on-YARN-td8751.html,
but I think spark code has changed a lot since then.
Any one could offer some guide? Thanks.
