---------------------------------------------------------------
Hi,
I used the following options that allows both driver & executors use a custom
log4j.properties,
{code}
spark-submit \
--driver-java-options=-Dlog4j.configuration=file:///absolute/path/to/conf/log4j.properties
\
--files conf/log4j.properties \
--conf
"spark.executor.extraJavaOptions='-Dlog4j.configuration=log4j.properties'" \
...
{code}
I used a local log4j.properties file for the driver and the file in the
distributed cache (by --files option) for the executors.
As shown above, the paths to driver and executors are different.
I hope it might be useful to the others.
Edited 2017-07-26: log4j.configuration needs path in URI format. Therefore,
file:// prefix is necessary for driver option.

> Configurable log4j settings
> ---------------------------
>
> Key: SPARK-16784
> URL: https://issues.apache.org/jira/browse/SPARK-16784
> Project: Spark
> Issue Type: Improvement
> Affects Versions: 2.0.0, 2.1.0
> Reporter: Michael Gummelt
>
> I often want to change the logging configuration on a single spark job. This
> is easy in client mode. I just modify log4j.properties. It's difficult in
> cluster mode, because I need to modify the log4j.properties in the
> distribution in which the driver runs. I'd like a way of setting this
> dynamically, such as a java system property. Some brief searching showed
> that log4j doesn't seem to accept such a property, but I'd like to open up
> this idea for further comment. Maybe we can find a solution.
