copied!<p>Does anyone know how to get rid of the following warnings when starting accumulo:</p> <pre><code>log4j:WARN No appenders could be found for logger (org.apache.accumulo.start.classloader.AccumuloClassLoader). log4j:WARN Please initialize the log4j system properly. log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info. </code></pre> <p>I am running accumulo 1.4.0 hadoop 0.20.2 and zookeeper 3.3.3. I understand this warning happens because the class can not find the log4j.properties file and yes I have read <a href="http://logging.apache.org/log4j/1.2/manual.html" rel="nofollow">http://logging.apache.org/log4j/1.2/manual.html</a>. My log4j.properties file has the following lines copied from an accumulo 1.4.3 log4j file (I dont have the option to upgrade my system to 1.4.3):</p> <pre><code># default logging properties: # by default, log everything at INFO or higher to the console log4j.rootLogger=INFO,A1 # hide Jetty junk log4j.logger.org.mortbay.log=WARN,A1 # hide "Got brand-new compresssor" messages log4j.logger.org.apache.hadoop.io.compress=WARN,A1 # hide junk from TestRandomDeletes log4j.logger.org.apache.accumulo.server.test.TestRandomDeletes=WARN,A1 # hide almost everything from zookeeper log4j.logger.org.apache.zookeeper=ERROR,A1 # hide AUDIT messages in the shell, alternatively you could send them to a different logger log4j.logger.org.apache.accumulo.core.util.shell.Shell.audit=WARN,A1 # Send most things to the console log4j.appender.A1=org.apache.log4j.ConsoleAppender log4j.appender.A1.layout.ConversionPattern=%d{ISO8601} [%-8c{2}] %-5p: %m%n log4j.appender.A1.layout=org.apache.log4j.PatternLayout </code></pre> <p>I have put this log4j file everyone. In the accumulo/bin folder, in the accumulo/conf folder, in the accumulo/lib folder but can not get rid of this warning (I know it has to go on the accumulo class path but dont know where that is). I also can't pass a log4j.configuration option to the java compiler because the accmulo executable comes pre-compiled (I just run it).</p> <p>Thanks in advance for the help.</p> <p>EDIT: Below is the result of an "accumulo classpath" command on my system:</p> <pre><code>[admin-cloud@NODE1 bin]$ echo $ACCUMULO_HOME /accumulo/accumulo-1.4.0 [admin-cloud@NODE1 bin]$ accumulo classpath Accumulo List of classpath items are: file:/accumulo/accumulo-1.4.0/lib/commons-collections-3.2.jar file:/accumulo/accumulo-1.4.0/lib/commons-configuration-1.5.jar file:/accumulo/accumulo-1.4.0/lib/log4j-1.2.16.jar file:/accumulo/accumulo-1.4.0/lib/libthrift-0.6.1.jar file:/accumulo/accumulo-1.4.0/lib/commons-jci-core-1.0.jar file:/accumulo/accumulo-1.4.0/lib/commons-lang-2.4.jar file:/accumulo/accumulo-1.4.0/lib/commons-logging-api-1.0.4.jar file:/accumulo/accumulo-1.4.0/lib/accumulo-server-1.4.0.jar file:/accumulo/accumulo-1.4.0/lib/accumulo-start-1.4.0.jar file:/accumulo/accumulo-1.4.0/lib/commons-jci-fam-1.0.jar file:/accumulo/accumulo-1.4.0/lib/jline-0.9.94.jar file:/accumulo/accumulo-1.4.0/lib/examples-simple-1.4.0.jar file:/accumulo/accumulo-1.4.0/lib/cloudtrace-1.4.0.jar file:/accumulo/accumulo-1.4.0/lib/commons-logging-1.0.4.jar file:/accumulo/accumulo-1.4.0/lib/accumulo-core-1.4.0.jar file:/accumulo/accumulo-1.4.0/lib/commons-io-1.4.jar file:/zookeeper/zookeeper-3.3.6/zookeeper-3.3.6.jar file:/hadoop/hadoop-0.20.2/conf/ file:/hadoop/hadoop-0.20.2/hadoop-0.20.2-examples.jar file:/hadoop/hadoop-0.20.2/hadoop-0.20.2-test.jar file:/hadoop/hadoop-0.20.2/hadoop-0.20.2-tools.jar file:/hadoop/hadoop-0.20.2/hadoop-0.20.2-ant.jar file:/hadoop/hadoop-0.20.2/hadoop-0.20.2-core.jar file:/hadoop/hadoop-0.20.2/lib/log4j-1.2.15.jar file:/hadoop/hadoop-0.20.2/lib/jasper-runtime-5.5.12.jar file:/hadoop/hadoop-0.20.2/lib/slf4j-log4j12-1.4.3.jar file:/hadoop/hadoop-0.20.2/lib/commons-httpclient-3.0.1.jar file:/hadoop/hadoop-0.20.2/lib/mockito-all-1.8.0.jar file:/hadoop/hadoop-0.20.2/lib/jetty-6.1.14.jar file:/hadoop/hadoop-0.20.2/lib/oro-2.0.8.jar file:/hadoop/hadoop-0.20.2/lib/servlet-api-2.5-6.1.14.jar file:/hadoop/hadoop-0.20.2/lib/junit-3.8.1.jar file:/hadoop/hadoop-0.20.2/lib/commons-logging-api-1.0.4.jar file:/hadoop/hadoop-0.20.2/lib/commons-codec-1.3.jar file:/hadoop/hadoop-0.20.2/lib/core-3.1.1.jar file:/hadoop/hadoop-0.20.2/lib/jets3t-0.6.1.jar file:/hadoop/hadoop-0.20.2/lib/hsqldb-1.8.0.10.jar file:/hadoop/hadoop-0.20.2/lib/slf4j-api-1.4.3.jar file:/hadoop/hadoop-0.20.2/lib/jasper-compiler-5.5.12.jar file:/hadoop/hadoop-0.20.2/lib/jetty-util-6.1.14.jar file:/hadoop/hadoop-0.20.2/lib/commons-net-1.4.1.jar file:/hadoop/hadoop-0.20.2/lib/commons-logging-1.0.4.jar file:/hadoop/hadoop-0.20.2/lib/commons-cli-1.2.jar file:/hadoop/hadoop-0.20.2/lib/xmlenc-0.52.jar file:/hadoop/hadoop-0.20.2/lib/kfs-0.2.2.jar file:/hadoop/hadoop-0.20.2/lib/commons-el-1.0.jar </code></pre>
