I have updated the log4.properties.
Here is the output with log4j debug enabled:

As you can see, it's reading from the default log4j.property file.
Inside of which I have this:
# Define some default values that can be overridden by system properties
hbase.root.logger=DEBUG,console
hbase.security.logger=DEBUG,console
hbase.log.dir=.
hbase.log.file=hbase.log
root.logger=DEBUG.console
log4j.rootLogger=DEBUG,console
However as you can see, no debug info displayed.
Using your parameter seems to be working:

But still no debug info displayed. My goal is to display the debug logs of
NativeCodeLoader for its static piece, but so far, no luck...
