Question

我使用CDH（Cloudera Distribution Hadoop）当我启动hdsf时，没有namenode

  $ sbin/start-dfs.sh

JPS：

 hadoop@hekuang:~/app/hadoop-2.6.0-cdh5.7.0/sbin$ jps
10489 DataNode
10685 SecondaryNameNode
11469 Jps

和namenode这样的日志

芯-site.xml中

<configuration>
    <property>
        <name>fs.defaultFS</name>
        <value>hdfs://hekuang:8020</value>
    </property>
<property>
        <name>hadoop.tmp.dir</name>
        <value>/home/hadoop/app/tmp</value>
    </property>
</configuration>

hdfs-site.xml

<configuration>

<property>
        <name>dfs.replication</name>
        <value>1</value>
    </property>
</configuration>

我尝试删除/ home / hadoop / app / tmp，然后重启，tbut也没有namenode。

如果删除

<property>
    <name>hadoop.tmp.dir</name>
    <value>/home/hadoop/app/tmp</value>
</property>

来自core-site.xml，并使用默认目录然后有namenode而没有DataNode

Answer 1

试试这个：

rm -rf / home / hadoop / app / tmp / *
hadoop namenode -format
启动Hadoop服务!!! start-all.sh

希望这会有所帮助!!!干杯!!!

无法启动namenode。目录处于不一致状态：存储目录不存在或无法访问
