I am trying to format the NN as wanted to do the HA setup through NFS.

steps - Taken 3 systems (vm11,vm12 and vm13) I made nfs server as vm13 and nfs is working fine ..ALL the systems are in sync with the NFS server, All good this point But when trying to do the NN HA setup  i am unable to format the NN getting the error as below.

Now i am providing the configuration files-: Both configuration files are same in vm11 and vm12 but while formating the NN give the error, could you please help me here.

Make the following changes to your configuration file and see if it works.

core-site.xml

<configuration>

<property>
<name>fs.defaultFS</name>
<value>hdfs://master:9000</value>
<description>The name of default file system</description>
</property>
<property>
    <name>hadoop.tmp.dir</name>
    <value>Give a path for temp dir</value>
   </property>
</configuration>

hdfs-site.xml

<property>

<name>dfs.namenode.name.dir</name>
<value>/hdfs/nameha</value>
<final>true</final>
</property>

<property>

<name>dfs.datanode.data.dir</name>
<value>/hdfs/dataha</value>
<final>true</final>
</property>

Hi,

  • In hdfs-site.xml , put the following property:
<property>
    <name>dfs.name.dir</name>
    <value>/<hadoop installation path>/hadoop-1.2.1/name/data</value>
</property>

where this is the path to write namenode metadata , run

  • ~$ stop-all.sh

  • Change directory permission to give user full access:

~$sudo chmod 750 /<hadoop installation path>/hadoop-1.2.1/name/data

  • format the name node

~$ hadoop namenode -format

  • start all hadoop daemons 

~$ start-all.sh
  • make sure you check all the daemons are started:
~$ jps
