> Today users are using {{sc.setLogLevel}} to configure the current log level 
> using {{SparkContext}} accessible from within the {{{}SparkSession{}}}. It is 
> a convenient alternative to directly depending on the Log4j mechanism like 
> statically changing the {{log4j.xml}} or dynamically invoke the Log4j API.
> It would be great to allow the configuration of the log level using a static 
> Spark conf that has the same kind of simplicity, which comes in handy when we 
> don't want to manually change the {{{}log4j.xml{}}}. This is particularly 
> helpful in the Spark Connect scenario where there’s no way for the client to 
> call {{setLogLevel}} because {{SparkContext}} is not yet supported in its 
> API, and when it connects to a platform where it can't easily change the 
> Log4j config file.
> ./bin/pyspark --conf spark.log.level ERROR
