No log4j2 configuration file found when trying to load test data from X-pack learning tutorial

@Ferrow

im having trouble getting data loaded for training purpose with the x-pack tutorial. (Lab 1) Im not sure where to start with this error since the files it mentions are in the correct places.
here is what my terminal have to say:

root@Infowise:/usr/share/logstash/bin# cat stocks.csv | ./logstash -f stocks.conf
ERROR StatusLogger No log4j2 configuration file found. Using default configuration: logging only errors to the console.

It is a known issue and can be ignored as recommended in this thread.
