我使用本教程设置并配置了一个多节点Hadoop集群.

当我输入start-all.sh命令时,它会显示正确初始化的所有进程,如下所示:

starting namenode, logging to /usr/local/hadoop/libexec/../logs/hadoop-root-namenode-jawwadtest1.out
jawwadtest1: starting datanode, logging to /usr/local/hadoop/libexec/../logs/hadoop-root-datanode-jawwadtest1.out
jawwadtest2: starting datanode, logging to /usr/local/hadoop/libexec/../logs/hadoop-root-datanode-jawwadtest2.out
jawwadtest1: starting secondarynamenode, logging to /usr/local/hadoop/libexec/../logs/hadoop-root-secondarynamenode-jawwadtest1.out
starting jobtracker, logging to /usr/local/hadoop/libexec/../logs/hadoop-root-jobtracker-jawwadtest1.out
jawwadtest1: starting tasktracker, logging to /usr/local/hadoop/libexec/../logs/hadoop-root-tasktracker-jawwadtest1.out
jawwadtest2: starting tasktracker, logging to /usr/local/hadoop/libexec/../logs/hadoop-root-tasktracker-jawwadtest2.out

但是,当我输入jps命令时,我得到以下输出:

31057 NameNode
4001 RunJar
6182 RunJar
31328 SecondaryNameNode
31411 JobTracker
32119 Jps
31560 TaskTracker

如您所见,没有运行datanode进程.我尝试配置单节点群集但遇到了同样的问题.有人会知道这里可能出现什么问题吗？是否有任何配置文件未在教程中提及或我可能已查看过？我是Hadoop的新手,有点迷失,任何帮助都会非常感激.

编辑:hadoop-root-datanode-jawwadtest1.log:

STARTUP_MSG:   args = []
STARTUP_MSG:   version = 1.0.3
STARTUP_MSG:   build = https://svn.apache.org/repos/asf/hadoop/common/branches/$

我正在尝试在我的PC上设置单节点Hadoop 2.6.0群集.

在访问http:// localhost:8088/cluster时,我发现我的节点被列为"不健康的节点".

在运行状况报告中,它提供错误:

1/1 local-dirs are bad: /tmp/hadoop-hduser/nm-local-dir; 
1/1 log-dirs are bad: /usr/local/hadoop/logs/userlogs

怎么了？
