Question

我正在使用ubuntu 14.04。 CDH4.7 我按照以下链接中给出的步骤进行安装 http://www.cloudera.com/content/cloudera-content/cloudera-docs/CDH4/latest/CDH4-Quick-Start/cdh4qs_topic_3_2.html 问题是我无法启动数据节点。我收到错误

naveensrikanthd@ubuntu:/$ for x in `cd /etc/init.d ; ls hadoop-hdfs-*` ; do sudo service $x start ; done
[sudo] password for naveensrikanthd: 
 * Starting Hadoop datanode: 
starting datanode, logging to /var/log/hadoop-hdfs/hadoop-hdfs-datanode-ubuntu.out

SLF4J: Defaulting to no-operation (NOP) logger implementation

naveensrikanthd@ubuntu:/$ jps

没有Hadoop进程正在运行，上面[slf4J]给出的这三个语句在namenode，datanode之间进行了混乱：

下面给出的是路径的日志文件： /var/log/hadoop-hdfs/hadoop-hdfs-datanode-ubuntu.out SLF4J：无法加载类＆＃34; org.slf4j.impl.StaticLoggerBinder＆＃34;。 SLF4J：默认为无操作（NOP）记录器实现 ulimit -a for user hdfs

我应该怎么做才能摆脱这个错误，任何人都可以帮助我们渡过这个错误

Answer 1

输出显示实际上名称节点已在运行。你应该仔细检查你认为他们应该在哪里运行以及你的配置说什么，因为它说你已经成功了。

log4j的错误与Hadoop功能无关。

Hadoop CDH4错误：SLF4J：无法加载类“org.slf4j.impl.StaticLoggerBinder”
