I have a solution. > Assume I stand in the root directory of the incubator-flink repo.
mkdir flink-addons/flink-spargel/src/main/resources cp ./flink-examples/flink-java-examples/src/main/resources/log4j.properties flink-addons/flink-spargel/src/main/resources/ (This file contains 1 line: log4j.rootLogger=OFF ) This prevents any log outputs. However, if I also set the JVM argument (in eclipse Run/Configurations/Arguments/VM arguments): -Dlog4j.configuration="/home/sudocker/git/incubator-flink/flink-addons/flink-spargel/src/main/resources/log4j.properties" then I get the warning: log4j:WARN No appenders could be found for logger (org.apache.flink.runtime.blob.BlobServer). log4j:WARN Please initialize the log4j system properly. log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.
