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

<property>
   <name>dfs.name.dir</name>
   <value>/home/hduser/data/dfs/namenode</value>
</property>

<property>
   <name>dfs.data.dir</name>
   <value>/home/hduser/data/dfs/datanode</value>
</property>

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

I tried formatting the namenode and starting again.But nothing happened. I changed my directory owner permission to 755 and tried again but still the issue did not resolve the issue.
I exhausted all the The suggestions given on this blog bur it did not help. I though all the possible solution and tried so may times to solve it but still am not able to do that.The same issue is coming again and again. Here is the detailed error msg:

Answer 1

您可以尝试删除namenode存储目录/ home / hduser / data / dfs / namenode，然后格式化namenode吗？
