hadoop/hdfs/name is in an inconsistent state: storage directory(hadoop/hdfs/data/) does not exist or is not accessible

I have tried all the different solutions provided at stackoverflow on this topic, but of no help Asking again with the specific log and the details

Any help is appreciated

I have one master node and 5 slave nodes in my Hadoop cluster. ubuntu user and ubuntu group is the owner of the ~/Hadoop folder Both the ~/hadoop/hdfs/data & ~/hadoop/hdfs/name folder exist

and permission for both the folders are set to 755

successfully formated the namenode before starting the script start-all.sh

THE SCRIPT FAILS TO LAUNCH THE "NAMENODE"

These are running at the master node

ubuntu@master:~/hadoop/bin$ jps

7067 TaskTracker
6914 JobTracker
7237 Jps
6834 SecondaryNameNode
6682 DataNode

ubuntu@slave5:~/hadoop/bin$ jps

31438 TaskTracker
31581 Jps
31307 DataNode

Below is the log from name-node log files.

You can follow given below steps to remove this error:

  1. Stop all hadoop daemons
  2. Delete all files from given below directory: /tmp/hadoop-{user}/dfs/name/current and /tmp/hadoop-{user}/dfs/data/current where user is the user with which you logged in into the box.
  3. Format namenode
  4. Start all services
  5. You will now see a new file VERSION created in directory /tmp/hadoop-/dfs/name/current

One thing to notice here is that value of Cluster ID in file /tmp/hadoop-eip/dfs/name/current/VERSION must be same as in /tmp/hadoop-eip/dfs/data/current/VERSION

Had similar problem, I formatted the namenode then started it

Hadoop namenode -format
hadoop-daemon.sh start namenode

1) name node directory you should be owner and give chmod 750 appropriately
2)stop all services
3)use hadoop namenode -format to format namenode
4)add this to hdfs-site.xml

<property>
    <name>dfs.data.dir</name>
    <value>path/to/hadooptmpfolder/dfs/name/data</value> 
    <final>true</final> 
    </property> 
    <property> 
    <name>dfs.name.dir</name>
    <value>path/to/hadooptmpfolder/dfs/name</value> 
    <final>true</final> 
</property>

5) to run hadoop namenode -format add export PATH=$PATH:/usr/local/hadoop/bin/ in ~/.bashrc wherever hadoop is unzip add that in path

Removed the "file:" from the hdfs-site.xml file

[WRONG HDFS-SITE.XML]

  <property>
  <name>dfs.namenode.name.dir</name>
  <value>file:/home/hduser/mydata/hdfs/namenode</value>
  </property>
  <property>
  <name>dfs.datanode.data.dir</name>
  <value>file:/home/hduser/mydata/hdfs/datanode</value>
  </property>

[CORRECT HDFS-SITE.XML]

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


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

Thanks to Erik for the help.

run these commands on terminal

$ cd ~
$ mkdir -p mydata/hdfs/namenode
$ mkdir -p mydata/hdfs/datanode

give permission to both directory 755

then,

Add this property in conf/hdfs-site.xml

  <property>
 <name>dfs.namenode.name.dir</name>
 <value>file:/home/hduser/mydata/hdfs/namenode</value>
</property>


<property>
 <name>dfs.datanode.data.dir</name>
 <value>file:/home/hduser/mydata/hdfs/datanode</value>
</property>

if not work ,then

stop-all.sh
start-all.sh
