Is there any way to silence these? $ java -jar avro-tools-1.8.1.jar tojson foo log4j:WARN No appenders could be found for logger (org.apache.hadoop.metrics2.lib.MutableMetricsFactory). log4j:WARN Please initialize the log4j system properly. log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.
Looks like avro-tools used to include<https://issues.apache.org/jira/browse/AVRO-758> log4j config. -Isaac Levy OS X el cap, java 1.8.0_92
