I noticed this problem when I tried to execute map reduce in R and failed to talk to JT and TT. This happened after I changed some config files, but unfortunately, I forgot how to change it back (my bad)!!

3) And here is my /etc/hosts file:
127.0.0.1 localhost
172.16.1.39 rhadoop
4) And my config in core-site.xml:
<property>
<name>fs.default.name</name>
<value>hdfs://rhadoop:8020</value>
</property>
5) And my mapred-site.xml:
<configuration>

<value>rhadoop:8021</value>
</property>

</configuration>
And one thing to mention is I checked the Wrong FS error for JT online, but most of them are like:
Wrong FS: hdfs:xxxxxxxxxxxxx, expected: xxxxxxxxx
ked But mine is like Wrong FS: file:xxxxxxxxxxx.
Can anyone help me with the configuration thing here?
I found the problem. In file /etc/hadoop/conf/hdfs-site.xml, there is one attribute:
<property>
<name>hadoop.tmp.dir</name>
<value>/var/lib/hadoop-hdfs/cache/${user.name}</value>
</property>
When I made some change, I carelessly changed the value to:
file:///var/lib/hadoop-hdfs/cache/${user.name}
which caused my problem!
Looks like you do not have proper permissions on the directory file:///var/lib/hadoop-hdfs/cache/mapred/mapred/local. Have you changed anything in your mapred-site.xml file?Specially the property mapred.local.dir?Showing us the JT and TT log files would be helpful.

Now it works well I only leave these lines in my hdfs-site.xml
<property>
<name>dfs.replication</name>
<value>2</value>
</property>
Is this going to pose problems ?
On the graphical interface of my cluster I see only a single datanode
you can see datanodes information her enter image description here
Thnak you
Property fs.default.name is deprecated. Try below instead.
<property>
<name>fs.defaultFS</name>
<value>hdfs://NAME_NODE_HOST:8020</value>
</property>
After looking at the logs:
Looks like you need to format the namenode.
Please try iceberg's solution at
Datanode not starts correctly
when I execute jps command datanode and nodemanagger appears, but it seems that is not starting correctly, because if I check logs it seems that they arent running correctly.
In the namenode node when I format namenode and start the cluster I get a Version file in namenodefolder created automatically as I set in hdfs-site.xml:
clusterID=CID-76572234-4ef7-4e6a-8ec5-1f54fe22b17d
cTime=0
storageType=NAME_NODE
blockpoolID=BP-141486958-10.17.0.88-1463916426343
layoutVersion=-63
But in the node where is datanode this file its not created, the folder datanode that I set in hdfs-site.xml is created but its empty inside, I dont know if it is normal.

Do you understand why its not working?
After looking at datanode logs it looks like the error is coming because of NameNode. It seems that namenode is down. Since NameNode is down, Datanode is not able to start properly.
Here is what you can do :
A. start the namenode.
B. verify that namenode is running properly.
C. start the datanode. verify it started properly.
D. Run your spark application
Edited mapred-site.xml,core-site.xml,hadoop-env.sh,hdfs-site.xml,masters and slaves.
I have 1 DataNode and 2 Namenodes.Both of them started successfully and I am able to see it in browser.
Started start-mapred.sh and it started JobTracker and TaskTracker on the Namenode but unable to start Tasktracker on the datanaode.
Started Tasktracker and the following is the output.

Though quite late to answer this, still does your mapred-site.xml contain mapred.job.tracker property ?
My job tracker runs on 8021, so the configuration is as follows:
<configuration>
<property>
<name>mapred.job.tracker</name>
<value>http://localhost:8021</value>
</property>
</configuration>
I faced such an issue due to missing properties.
I am currently using Hadoop-2.0.3-alpha and after I could work perfectly with HDFS (copying files into HDFS, getting success from an external framework, using the webfrontend), after a new start of my VM, the datanode process is stopping after a while. The namenode process and all yarn processes work without a problem. I installed Hadoop in a folder under an additional user, as I also still have installed Hadoop 0.2, which worked fine too.
Taking a look at the log-file of all datanode processes I got the following information:

Any ideas? May be I made a mistake during the installation process? But it is strange, that it worked once. I also have to say, that if I am logged in as my additional user to execute the commands ./hadoop-daemon.sh start namenode and the same with the datanode, I need to add sudo.
I used this installation guide: http://jugnu-life.blogspot.ie/2012/0...rial-023x.html
By the way, I use the Oracle Java-7 version.
The problem could be that the namenode was formatted after the cluster was set up and the datanodes were not, so the slaves are still referring to the old namenode.
We have to delete and recreate the folder /home/hadoop/dfs/data on the local filesystem for the datanode.
Check your hdfs-site.xml file to see where dfs.data.dir is pointing to
and delete that folder
and then restart the datanode daemon on the machine
The steps above should recreate the folder and resolve the problem.
Please share your config info if the instructions above do not work.
DataNode dies because of incompatible Clusterids. To fix this problem
If you are using hadoop 2.X, then you have to delete everything in the folder that you have specified in hdfs-site.xml - "dfs.datanode.data.dir" (but NOT the folder itself).
The ClusterID will be maintained in that folder. Delete and restart dfs.sh. This should work!!!
You need to delete both
C:\hadoop\data\dfs\datanode and
C:\hadoop\data\dfs\namenode folders.
If you don't have this folders - open your C:\hadoop\etc\hadoop\hdfs-site.xml file and get paths for this folders for next deletion. For me it says:
<property>
<name>dfs.namenode.name.dir</name>
<value>file:/hadoop/data/dfs/namenode</value>
</property>
<property>
<name>dfs.datanode.data.dir</name>
<value>file:/hadoop/data/dfs/datanode</value>
</property>
Run command for Format namenodec:\hadoop\bin>hdfs namenode -format
Now it should work!
I think the recommended way of doing this without deleting the data directory is to simply change the clusterID variable in the datanode's VERSION file.
If you look in your daemons directory, you will see the datanode directory exmaple
data/hadoop/daemons/datanode
The VERSION file should look like this.
cat current/VERSION
#Tue Oct 14 17:31:58 CDT 2014
storageID=DS-23bf7f3a-085c-4531-808f-801ff6d52d14
clusterID=CID-bb3547b0-03e4-4588-ac25-f0299ff81e4f
cTime=0
datanodeUuid=63154929-ae68-4149-9f75-9a6558545041
storageType=DATA_NODE
layoutVersion=-55
You need to change the clusterId to the first value in the output of the message so in your case that would be CID-1745a89c-fb08-40f0-a14d-d37d01f199c3 instead of CID-bb3547b0-03e4-4588-ac25-f0299ff81e4f
The updated version should appear like this with the altered clusterId
cat current/VERSION
#Tue Oct 14 17:31:58 CDT 2014
storageID=DS-23bf7f3a-085c-4531-808f-801ff6d52d14
clusterID=CID-1745a89c-fb08-40f0-a14d-d37d01f199c3
cTime=0
datanodeUuid=63154929-ae68-4149-9f75-9a6558545041
storageType=DATA_NODE
layoutVersion=-55
Restart hadoop and the datanode should start just fine.
I am getting an error in starting the data node while initiating the single node cluster set up on my machine

Any idea about how to resolve this error?
Ok got the problem solved.
Since I was using my single-node cluster through a network proxy, I had added the following property line to $HADOOP_HOME/conf/mapred-site.xml to by-pass proxy server while communicating across Hadoop daemons.
However, this time I was trying out on a direct internet connection, so had to comment out the property that I added in mapred-site.xml.
Below is the property from mapred-site.xml that I commented out:
<!--
<property>
<name>hadoop.rpc.socket.factory.class.default</name>
<value>org.apache.hadoop.net.StandardSocketFactory</value>
<final>true</final>
<description>
Prevent proxy settings set up by clients in their job configs from affecting our connectivity.
</description>
</property>
-->
