I want to output the steps of execution of my UDF but I cant find the logs, I searched the region log in /usr/local/hbase/logs/
....
public static final Log LOG = LogFactory.getLog(MyUDF.class);
....
    public boolean evaluate(Tuple tuple, ImmutableBytesWritable ptr) {
        LOG.info("UDF execution started");

....
