su - hadoop
Enter password for hadoop user.
sudo mkdir /usr/local/hdfs/datanode
sudo chmod -R 777 /usr/local/hdfs/datanode

STEP 2: Change the value for dfs.datanode.data.dir in hdfs-site.xml as:
Change this
/hadoopuser/hdfs/datanode
to
/usr/local/hdfs/datanode
Now, restart your hadoop processes.
NOTE: In "su - hadoop", hadoop is my hadoop username. If hadoop is not your username, change it to your username which you are

Your jobtracker and tasktracker are all not start, how can you get the their log files.

I want to let the dataNode and nameNode directory in my windows directory(such as in mnt/d/hadoop/hadoop-2.7.1/tmp) but failed.
I tried to use chmod 777 -R hadoop /mnt/d/hadoopbut it still can't start. Also I tired to delete the tmp directory and reformat namenode.
But when I change the directory to /home/hadoop/tmp(my wsl directory), dataNode can start normally.
According to the log file, I think this is a problem of authority but I don't konw why. How can I fix this?
I have solved this problem, this is caused by windows authority.
You can't change the file's authority under /mnt in wsl.
When you use chown or chmod, they actually don't work.
You need to use the following instructions first.
sudo umount /mnt/d
sudo mount -t drvfs D: /mnt/d -o metadata
Then you can change the file's authority in wsl.
You can get more information here: https://devblogs.microsoft.com/commandline/chmod-chown-wsl-improvements/
I tried to set up Hadoop 2.6.1 based on instructions from here
But my data node is not up. When I do JPS , I get only the below process
▶ jps

7744 NameNode

Please help what's that I could be missing
1)Make sure the directory has right owner and permissions.
$ sudo chown -R hduser:hadoop /home/vinod/.hadoopdata/hdfs/datanode
2) Delete the contents given in tmp directory. It is the parameter given for hadoop.tmp.dir
3) Format the namenode.
Start all the process again. Hope this helps...
I am using ubuntu 14.04 LTS Java version 8 and Hadoop 2.5.1 for installation. I followed this guide to install all the components. Sorry for not using michael noll's.
Now the problem that i face is when i do start-dfs.sh i get the following message

The ideal output should have datanode in it, but it is not there. Googling and SOing a bit i found out the error is looged in the logs so here are the logs for datanode.(Only error part if you need more let me know)

Now my doubt is how to make it valid.
Help is appreciated.
P.S. I tried a lot of forums, SO post none of them could give me solution to this problem. Hence the question.
First delete all contents from hdfs folder:
Value of <name>hadoop.tmp.dir</name>
rm -rf /usr/local/hadoop_store
Make sure that dir has right owner and permission /usr/local/hadoop_store
hduser#localhost$sudo chown hduser:hadoop -R /usr/local/hadoop_store
hduser#localhost$sudo chmod 777 -R /usr/local/hadoop_store
Format the namenode:
hduser#localhost$hadoop namenode -format
Start all processes again
I also got the same problem,and I fixed them by changing the owner of those working directory.Although you have permissions 777 to these two directory,framework will not be able to use it unless you change the owner to hduser.
$ sudo chown -R hduser:hadoop /usr/local/hadoop/yarn_data/hdfs/namenode
$ sudo chown -R hduser:hadoop /usr/local/hadoop/yarn_data/hdfs/datanode
After this,you again start your cluster and you should see datanode running.
first stop all the entities like namenode, datanode etc. (you will
be having some script or command to do that)
Format tmp directory
Go to /var/cache/hadoop-hdfs/hdfs/dfs/ and delete all the contents in the directory manually
Now format your namenode again
start all the entities then use jps command to confirm that the datanode has been started
Now run whichever application you may like or have.
Hope this helps.
When using cloudera, I had the same problem.
* chown hdfs:hadoop all_hdfs_directories
chown 997:996 all_hdfs_directories (if users don't exist yet)
* chmod 0755 is enough
* delete contents of directories if problem persists

Before formatting the namenode, delete the tmp folder(contains datanode and namenode) and then format the namenode.
And then start the hadoop services.
I am trying to install Hadoop 2.2.0 in pseudo-distributed mode. While I am trying to start the datanode services it is showing the following error, can anyone please tell how to resolve this?

You can do the following method,
copy to clipboard datanode clusterID for your example, CID-8bf63244-0510-4db6-a949-8f74b50f2be9
and run following command under HADOOP_HOME/bin directory
./hdfs namenode -format -clusterId CID-8bf63244-0510-4db6-a949-8f74b50f2be9
then this code formatted the namenode with datanode cluster ids.
You must do as follow :
bin/stop-all.sh
rm -Rf /home/prassanna/usr/local/hadoop/yarn_data/hdfs/*
bin/hadoop namenode -format
I had the same problem until I found an answer in this web site.
Whenever you are getting below error, trying to start a DN on a slave machine:
java.io.IOException: Incompatible clusterIDs in /home/hadoop/dfs/data: namenode clusterID= ****; datanode clusterID = ****
It is because after you set up your cluster, you, for whatever reason, decided to reformat
your NN. Your DNs on slaves still bear reference to the old NN.
To resolve this simply delete and recreate data folder on that machine in local Linux FS, namely /home/hadoop/dfs/data.
Restarting that DN's daemon on that machine will recreate data/ folder's content and resolve
the problem.
Do following simple steps
Clear the data directory of hadoop
Format the namenode again
start the cluster
After this your cluster will start normally if you are not having any other configuration issue
DataNode dies because of incompatible Clusterids compared to the NameNode. To fix this problem you need to delete the directory /tmp/hadoop-[user]/hdfs/data and restart hadoop.
rm -r /tmp/hadoop-[user]/hdfs/data
I got similar issue in my pseudo distributed environment. I stopped cluster first, then I copied Cluster ID from NameNode's version file and put it in DataNode's version file, then after restarting cluster, its all fine.
my data path is here /usr/local/hadoop/hadoop_store/hdfs/datanode and /usr/local/hadoop/hadoop_store/hdfs/namenode.
FYI : version file is under /usr/local/hadoop/hadoop_store/hdfs/datanode/current/ ; likewise for NameNode.
Here, the datanode gets stopped immediately because the clusterID of datanode and namenode are different. So you have to format the clusterID of namenode with clusterID of datanode
Copy the datanode clusterID for your example, CID-8bf63244-0510-4db6-a949-8f74b50f2be9 and run following command from your home directory. You can go to your home dir by just typing cd on your terminal.
From your home dir now type the command:
hdfs namenode -format -clusterId CID-8bf63244-0510-4db6-a949-8f74b50f2be9
Delete the namenode and datanode directories as specified in the core-site.xml.
After that create the new directories and restart the dfs and yarn.
I also had the similar issue.
I deleted namenode and datanode folders from all the nodes, and rerun:
$HADOOP_HOME/bin> hdfs namenode -format -force
$HADOOP_HOME/sbin> ./start-dfs.sh
$HADOOP_HOME/sbin> ./start-yarn.sh
To check the health report from command line (which I would recommend)
$HADOOP_HOME/bin> hdfs dfsadmin -report
and I got all the nodes working correctly.
I had same issue for hadoop 2.7.7
I removed the namenode/current & datanode/current directory on namenode and all the datanodes
Removed files at /tmp/hadoop-ubuntu/*
then format namenode & datanode
restart all the nodes.
things work fine
steps:
stop all nodes/managers then attempt below steps
rm -rf /tmp/hadoop-ubuntu/* (all nodes)
rm -r /usr/local/hadoop/data/hdfs/namenode/current (namenode: check hdfs-site.xml for path)
rm -r /usr/local/hadoop/data/hdfs/datanode/current (datanode:check hdfs-site.xml for path)
hdfs namenode -format (on namenode)
hdfs datanode -format (on namenode)
Reboot namenode & data nodes
There's been different solutions to this problem, but I tested another easy solution and it worked like a charm :
So if someone get the same error, you just need to change the clusterID in the datanodes with clusterID of the namenode in the VERSION file.
With your case, here's were you can change it on datanode side :
namenode clusterID = CID-fb61aa70-4b15-470e-a1d0-12653e357a10; datanode clusterID = CID-8bf63244-0510-4db6-a949-8f74b50f2be9
Backup the current VERSION : cp /home/prassanna/usr/local/hadoop/yarn_data/hdfs/datanode/current/VERSION /home/prassanna/usr/local/hadoop/yarn_data/hdfs/datanode/current/VERSION.BK
vim /home/prassanna/usr/local/hadoop/yarn_data/hdfs/datanode/current/VERSION and change
clusterID=CID-8bf63244-0510-4db6-a949-8f74b50f2be9
with
clusterID=CID-fb61aa70-4b15-470e-a1d0-12653e357a10
Restart the datanode and it should work.
