namenode,datanode不使用jps列出

Question

环境:ubuntu 14.04,hadoop 2.6

当我键入start-all.sh和jps,DataNode不会列出终端上

>jps
9529 ResourceManager
9652 NodeManager
9060 NameNode
10108 Jps
9384 SecondaryNameNode

根据这个答案:Datanode进程没有在Hadoop中运行

我尝试了最好的解决方案

• bin/stop-all.sh (or stop-dfs.sh and stop-yarn.sh in the 2.x serie)
• rm -Rf /app/tmp/hadoop-your-username/*
• bin/hadoop namenode -format (or hdfs in the 2.x series)

但是,现在我明白了:

>jps
20369 ResourceManager
26032 Jps
20204 SecondaryNameNode
20710 NodeManager

如你所见,即使NameNode是失踪,请帮助我.

Answer 1

FATAL org.apache.hadoop.hdfs.server.datanode.DataNode:secureMain中的异常java.io.IOException:dfs.datanode.data.dir中的所有目录都无效:"/ usr/local/hadoop_store/hdfs/datanode /"

此错误可能是由于/usr/local/hadoop_store/hdfs/datanode/文件夹的权限错误.

FATAL org.apache.hadoop.hdfs.server.namenode.NameNode:无法启动namenode.org.apache.hadoop.hdfs.server.common.InconsistentFSStateException:目录/ usr/local/hadoop_store/hdfs/namenode处于不一致状态:存储目录不存在或无法访问.

此错误可能是由于/usr/local/hadoop_store/hdfs/namenode文件夹的权限错误或它不存在.要解决此问题,请遵循以下选项:

选项I:

如果您没有该文件夹/usr/local/hadoop_store/hdfs,请按如下所示创建并授予该文件夹的权限:

sudo mkdir /usr/local/hadoop_store/hdfs
sudo chown -R hadoopuser:hadoopgroup /usr/local/hadoop_store/hdfs
sudo chmod -R 755 /usr/local/hadoop_store/hdfs

分别更改hadoopuser和hadoopgroup您的hadoop用户名和hadoop组名.现在,尝试启动hadoop进程.如果问题仍然存在,请尝试选项2.

方案二:

删除/usr/local/hadoop_store/hdfs文件夹的内容:

sudo rm -r /usr/local/hadoop_store/hdfs/*

更改文件夹权限:

sudo chmod -R 755 /usr/local/hadoop_store/hdfs

现在,启动hadoop进程.它应该工作.

注意:如果错误仍然存​​在,请发布新日志.

更新:

如果您尚未创建hadoop用户和组,请执行以下操作:

sudo addgroup hadoop
sudo adduser --ingroup hadoop hadoop

现在,更改/usr/local/hadoop和的所有权/usr/local/hadoop_store:

sudo chown -R hadoop:hadoop /usr/local/hadoop
sudo chown -R hadoop:hadoop /usr/local/hadoop_store

将您的用户更改为hadoop:

su - hadoop

输入您的hadoop用户密码.现在您的终端应该像:

hadoop@ubuntu:$

现在,键入:

$HADOOP_HOME/bin/start-all.sh

要么

sh /usr/local/hadoop/bin/start-all.sh

Answer 2

我面临类似的问题，jps是不显示的DataNode。

删除hdfs文件夹的内容和更改文件夹权限对我来说很有效。

sudo rm -r /usr/local/hadoop_store/hdfs/*
sudo chmod -R 755 /usr/local/hadoop_store/hdfs    
hadoop namenode =format
start-all.sh
jps
