Hadoop suppress security logger log level

[#1]

Hi Team,

I want to change the log level of the Hadoop security logger from INFO to ERROR. I've exported the following environment variable for that

export HADOOP_NAMENODE_OPTS="-Dhadoop.security.logger=ERROR,RFA ${HADOOP_NAMENODE_OPTS}"

I can see the new parameter has been reflected in the command line

hdfs 13048 2.1 0.7 3899916 509000 ? Sl 01:22 0:29 /usr/lib/jvm/java-11-openjdk-amd64/bin/java -Dproc_namenode -Djava.net.preferIPv4Stack=true -Dhdfs.audit.logger=INFO,NullAppender -Dhadoop.security.logger=ERROR,RFA -Dyarn.log.dir=/var/log/hadoop-hdfs -Dyarn.log.file=hadoop-hdfs-namenode-hadoop-master-1.log -Dyarn.home.dir=/usr/lib/hadoop-yarn -Dyarn.root.logger=INFO,console -Djava.library.path=/usr/lib/hadoop/lib/native -Xmx2048m -Dhadoop.log.dir=/var/log/hadoop-hdfs -Dhadoop.log.file=hadoop-hdfs-namenode-hadoop-master-1.log -Dhadoop.home.dir=/usr/lib/hadoop -Dhadoop.id.str=hdfs -Dhadoop.root.logger=ERROR,RFA -Dhadoop.policy.file=hadoop-policy.xml org.apache.hadoop.hdfs.server.namenode.NameNode

But still, I can see the INFO level logs from the security logger in the log file

[Socket Reader #1 for port 9820] INFO SecurityLogger.org.apache.hadoop.ipc.Server - Auth successful for hdfs/hadoop-master-1.hadoop.default.svc.cluster.local@CLUSTER.LOCAL (auth:KERBEROS)
[Socket Reader #1 for port 9820] INFO SecurityLogger.org.apache.hadoop.security.authorize.ServiceAuthorizationManager - Authorization successful for hdfs/hadoop-master-1.hadoop.default.svc.cluster.local@CLUSTER.LOCAL (auth:KERBEROS) for protocol=interface org.apache.hadoop.ha.HAServiceProtocol

Anything I'm missing here?

Hi @akshaydalvi , I am not sure if you are using Cloudera Manager or not. Please confirm. Make sure your log4j.properties reflects what you are trying to change. You could add "hadoop.security.logger=ERROR,RFAS" line under the log4j safety valve. Be sure that you are using the right RollingAppender name RFA or RFAS. We generally use RFAS for SecurityLogger as shown below snippet.

hadoop.security.log.file=SecurityAuth-${user.name}.audit
log4j.appender.RFAS=org.apache.log4j.RollingFileAppender
log4j.appender.RFAS.File=/var/log/hadoop-hdfs/SecurityAuth-${user.name}.audit

Here is how we configure the log4j safety valve in Cloudera Manager under HDFS -> Configuration
