when try to Format namenode ,its format the tempory one

[#1]

I need to formate the namenode. So i use below command to formate the namenode.

./bin/hadoop namenode -format

When i run the above command it gives me ,it formatted below formatted.But my namenode is located in different directory.Why its formatting temp forlder namenode.

17/02/18 10:17:17 INFO common.Storage: Storage directory /tmp/hadoop-aruna/dfs/name has been successfully formatted.

Below is the my .bashrc file configuration

#SET Hadoop Related Envirment Variable
export HADOOP_HOME=/home/aruna/hadoop-2.7.3
export HADOOP_CONF_DIR=/home/aruna/hadoop-2.7.3/etc/hadoop
export HADOOP_MAPRED_HOME=/home/aruna/hadoop-2.7.3
export HADOOP_COMMON_HOME=/home/aruna/hadoop-2.7.3
export HADOOP_HDFS_HOME=/home/aruna/hadoop-2.7.3
export YARN_HOME=/home/aruna/hadoop-2.7.3
export HADOOP_COMMON_LIB_NATIVE_DIR=$HADOOP_HOME/lib/native
export HADOOP_OPTS="-Djava.library.path=$HADOOP_HOME/lib/native"

#Set Java Home
export JAVA_HOME=/usr/lib/jvm/java-7-oracle
export PATH=$PATH:/usr/lib/jvm/java-7-oracle/bin

#Set Hadoop bin  directory PATH
export PATH=$PATH:/home/aruna/hadoop-2.7.3/bin
export HADOOP_PID_DIR=/home/aruna/hadoop-2.7.3/hadoop2_data/hdfs/pid

normally namenode should be in below path.

/home/aruna/hadoop-2.7.3/hadoop2_data/hdfs/namenode

@Aruna Sameera

The "hadoop namenode -format" command formats the specified NameNode. It starts the NameNode, formats it and then shut it down.

dfs.namenode.name.dir: Determines where on the local filesystem the DFS name node should store the name table(fsimage). If this is a comma-delimited list of directories then the name table is replicated in all of the directories, for redundancy. with default value ${hadoop.tmp.dir}/dfs/name.

dfs.datanode.data.dir: (default: file://${hadoop.tmp.dir}/dfs/data) - Determines where on the local filesystem an DFS data node should store its blocks.

hadoop.tmp.dir: "/tmp/hadoop-${user.name}" (Default) - A base for other temporary directories.

.

Please check the values of above parameters defined in your core-site.xml/hdfs-site.xml

.

Ref:

https://hadoop.apache.org/docs/r2.7.3/hadoop-project-dist/hadoop-common/core-default.xml

The Default values are determined as mentioned in the link:

        <property>
          <name>dfs.namenode.name.dir</name>

Anyway i followed all the steps in below tutorial.

https://www.youtube.com/watch?v=l1QmEPEAems

And then when i try to run the sudo jps command it shows below result.

aruna@aruna:~/hadoop-2.7.3$ sudo jps

Only datanode is missing. How can i start datanode ?

[#4]

@Aruna Sameera

In order to start/stop datanode separately you can try using the "sbin/start-dfs.sh" and "sbin/stop-dfs.sh" scripts.

And if datanode is still not starting then check the datanode log.

I tried jay, But seems its not starting the datanode

@Aruna Sameera

Try using: "stop-all.sh" first to stop all processes.

Keep checking the logs (Specially the Datanode log/out)

Then try starting then using "start-all.sh". If datanode still does not stop then please share the out file of datanode.

Also try starting it using the following command to individually start them:

hadoop-daemon.sh start namenode
hadoop-daemon.sh start datanode

.

1) Stopping all

2) Start all

3)Check the status, but here Namenode missing now? but is above log shows starting namenode.

I stop all the demons and try format again as below

So what can i do for this "Incompatible clusterIDs" issue? if i reformate and start from the begining does this issue will resolve ?

@Aruna Sameera

Regarding your latest error:

 Incompatible clusterIDs in /home/aruna/hadoop-2.7.3/hadoop2_data/hdfs/datanode: namenode clusterID = CID-f597ff66-0d6a-4394-b038-02a4b51aa5be; datanode clusterID = CID-f4ecb1e1-ba90-4b03-a030-b8ef4e6b698f

.

Looks like your VERSION file has different cluster IDs present in NameNode and DataNode that need to be correct. So please check.

cat <dfs.namenode.name.dir>/current/VERSION
cat <dfs.datanode.data.dir>/current/VERSION 

Hence Copy the clusterID from namenode and put it in the VERSION file of datanode and then try again.
