Description

To make beeline as simple as possible, move its SLF4J logger implementation to SLFJ-Simple logger. This will allow users to change the logging level simply on the command line. Currently uses must create a Log4J configuration file which is way too advance/cumbersome for a data analyst that just wants to use SQL (and do some minor troubleshooting)

export HADOOP_CLIENT_OPTS="-Dorg.slf4j.simpleLogger.defaultLogLevel=debug"
