1.namenode启动失败,查看错误原因,是无法格式化,再看日志,根据日志提示,清空对应的目录,即可解决这个问题. 2.datanode启动失败: Can't open /var/run/cloudera-scm-agent/process/261-hdfs-DATANODE/supervisor.conf: Permission denied. cd到/var/run/cloudera-scm-agent/process/261-hdfs-DATANODE目录下,看到: -rw-------…

最近有安装了一次hadoop集群,NameNode启动失败,查看日志,找到以下原因: 遇到的异常1: org.apache.hadoop.hdfs.server.common.InconsistentFSStateException: Directory /tmp/hadoop-javoft/dfs/name is in an inconsistent state: storage di rectory does not exist or is not accessible.at org.apa…

问题导读: 1.Hadoop出现问题时,该如何入手查看问题?2.datanode无法启动,我们该怎么解决?3.如何动态加入DataNode或TaskTracker? 一.问题描述当我多次格式化文件系统时,如 root@localhost:/usr/local/hadoop-# bin/hadoop namenode -format 复制代码 会出现datanode无法启动,查看日志,发现错误为: -- ::, ERROR org.apache.hadoop.hdfs.server.datanod…

由于hadoop节点的磁盘满了,导致节点死掉,今天对其进行扩容.首先,将原节点的数据拷贝到目标节点下,从而避免数据的丢失,但是在执行hadoop_daemon.sh start datanode后没有启动datanode,查看log如下: 2014-04-17 11:44:06,200 WARN org.apache.hadoop.hdfs.server.datanode.DataNode: Invalid directory in dfs.data.dir: Incorrect permiss…

当我动态加入一个hadoop从节点的之后,出现了一个问题: [root@hadoop current]# hadoop-daemon.sh start datanode starting datanode, logging to /usr/local/hadoop1.1/libexec/../logs/hadoop-root-datanode-hadoop.out [root@hadoop ~]# jps jps命令发现没有datanode启动.所以去它提示的路径下查看了hadoop-root-…
