Hi all, I am trying to cut back on some of the logging noise from the Spark / Kafka frameworks by editing log4j.properties. However, it seems like package-specific customisations are ignored for inner classes. For example, the following configuration lines mostly work as expected, suppressing most logs from these packages below WARN level: log4j.logger.org.apache.spark=WARN log4j.logger.kafka.utils=WARN
However, I am still getting log messages at INFO from classes like: org.apache.spark.Logging$class kafka.utils.Logging$class I suspect it's because these are inner classes. It still happens even when I go up a level and add configurations like "log4j.logger.org=WARN". Is this a known bug in log4j? Is there any known way to suppress these, ideally through configuration rather than programmatically? Many thanks
