prophy Yan created HDFS-7657: -------------------------------- Summary: failed start datanode in secure mode with class not found err, but jar is in classpath Key: HDFS-7657 URL: https://issues.apache.org/jira/browse/HDFS-7657 Project: Hadoop HDFS Issue Type: Bug Components: datanode Affects Versions: 2.6.0 Environment: centos 6.5 hadoop-2.6.0 Reporter: prophy Yan
i use the root to start datanode in secure mode, but is doesn't start in jsvc.err ,the err is : "Service exit with a return value of 3 java.lang.ClassNotFoundException: org.apache.hadoop.hdfs.server.datanode.SecureDataNodeStarter" but the jar file is in the classpath i set the $hadoop_home/bin/hdfs to debug mode, it show the command is: /usr/bin/jsvc -Dproc_datanode -outfile /var/log/hadoop//jsvc.out -errfile /var/log/hadoop//jsvc.err -pidfile /var/run/hadoop/hadoop_secure_dn.pid -nodetach -user hdfs -cp '/usr/lib/hadoop/commons-daemon-1.0.15.jar:/etc/hadoop:/usr/lib/hadoop/share/hadoop/common/lib/*:/usr/lib/hadoop/share/hadoop/common/*:/usr/lib/hadoop/share/hadoop/hdfs:/usr/lib/hadoop/share/hadoop/hdfs/lib/*:/usr/lib/hadoop/share/hadoop/hdfs/*:/usr/lib/hadoop/share/hadoop/yarn/lib/*:/usr/lib/hadoop/share/hadoop/yarn/*:/usr/lib/hadoop/share/hadoop/mapreduce/lib/*:/usr/lib/hadoop/share/hadoop/mapreduce/*:/contrib/capacity-scheduler/*.jar' -Xmx1000m -Djava.net.preferIPv4Stack=true -Dhadoop.log.dir=/var/log/hadoop -Dhadoop.log.file=hadoop.log -Dhadoop.home.dir=/usr/lib/hadoop -Dhadoop.id.str=root -Dhadoop.root.logger=INFO,console -Djava.library.path=/usr/lib/hadoop/lib/native -Dhadoop.policy.file=hadoop-policy.xml -Djava.net.preferIPv4Stack=true -Dhadoop.log.dir=/var/log/hadoop/ -Dhadoop.id.str=hdfs -jvm server -Dhadoop.security.logger=ERROR,RFAS -Dhadoop.security.logger=INFO,NullAppender org.apache.hadoop.hdfs.server.datanode.SecureDataNodeStarter i add "for f in /usr/lib/hadoop/share/hadoop/common/*.jar; do export HADOOP_CLASSPATH=$HADOOP_CLASSPATH:$f done .......,and so on " to the hadoop-env.sh, then the datanode can start so is this mean the jsvc can not recognize the -cp 'hadoop_home/lib/*'? it just can recognize the -cp 'hadoop_home/lib/hadoop-hdfs.jar', like this? -- This message was sent by Atlassian JIRA (v6.3.4#6332)
