As you can see that all the processes are running.But when I go to log I found the below error;
ERROR org.apache.hadoop.hdfs.server.namenode.FSNamesystem: FSNamesystem initialization failed.
org.apache.hadoop.hdfs.server.common.InconsistentFSStateException: Directory /home/hduser/data/dfs/namenode is in an inconsistent state: storage directory does not exist or is not accessible.
I checked my .xml files configuration.Which is as follows;
mapre-site.xml
<property>
<name>mapred.job.tracker</name>
<value>172.16.76.1:9002</value>
</property>
core-site.xml
<property>
<name>fs.default.name</name>
<value>hdfs://localhost:9001</value>
</property>
HDFS-site.xml中
<property>
<name>dfs.name.dir</name>
<value>/home/hduser/data/dfs/namenode</value>
</property>
<property>

我試圖格式化NameNode和again.But開始什麼都沒有發生。 我將我的目錄擁有者權限更改爲755，然後再次嘗試，但仍然沒有問題 可解決問題。
我用盡了所有在這個博客上給出的建議bur它並沒有幫助。 我雖然所有可能的解決方案，並試圖可能時間來解決它，但仍然無法做 that.The同樣的問題來了一次又一次。 下面是詳細的錯誤信息：
