How to Disable or do minimal Logging for apache spark client Driver program? I
couldn't find this information on docs. By Driver program I mean the java
program where I initialize spark context. It produces lot of INFO messages but I
would like to know only when there is error or a Exception such as Nullpointer
exception and so on. I am also using spark standalone mode and I don't submit
jobs through command line. I just invoke public static void main() of my driver
program.
