I am new to Hadoop, so I would really appreciate any feedback on this issue.
The Hadoop setup seems fine. I am able to start it, but when I checked the web UI at: http://localhost:50070 or http://localhost:9870 it shows the site can't be reached. Similarly, to check Yarn with the web UI http://localhost:8088, I had the same problem.
command jps shows the following details:
50714 SecondaryNameNode
88442
51756 Jps
50589 DataNode
Namenode, ResourceManager, NodeManager are missing.
I have tried changing the port configuration, didn't help.
Reference: http://localhost:50070 does not work HADOOP
hadoop web UI at http://localhost:50070/ doesnt work
$ ./start-dfs.sh

Still cannot get the namenode started. The web UI still won't show up.
Update Here is the log file for the namenode:

/************************************************************
SHUTDOWN_MSG: Shutting down NameNode at Maggies-MacBook-Pro.local/10.0.0.73
************************************************************/
Try to format namenode and again start all those nodes using start-all.sh
Will solve the issue I guess
Execute ssh localhost, may be it will fail connect.
If it is failed to connect, then add ssh keys to your known host.
Then start ./start-dfs.sh.
In my case I run a fortune program in my .bashrc and prints some messages.
Seem like that output would impact Hadoop script. My current version is 3.3.0.
Could not parse line: *** seems to parse the output of something including that program and throws error. So I have to remove this and it's gone.
In normal account.
I created some directories.
/usr/local/hadoop-2.7.3/data/dfs/namenode
/usr/local/hadoop-2.7.3/data/dfs/namesecondary
/usr/local/hadoop-2.7.3/data/dfs/datanode
/usr/local/hadoop-2.7.3/data/yarn/nm-local-dir
/usr/local/hadoop-2.7.3/data/yarn/system/rmstore
And typed some commands
bin/hdfs namenode –format
sudo sbin/start-all.sh
jps
Then
In the normal account, I could see only jps.
In the root account, I could see Jps, DataNode, SecondaryNameNode, NodeManager and ResourceManager.
I have 2 questions.
Why can I see only jps in normal account?
Why is namenode not started?
Thanks for reading.
And if you help me, I will appreciate you.

Why can I see only jps in normal account?
As you have started the daemons with sudo, root user owns the processes. The command jps reports only the JVMs for which it has the access permissions. The normal account has no access for the processes owned by root.
Why is namenode not started?
java.io.IOException: NameNode is not formatted.
Namenode is not yet formatted. It is possible that you have missed to provide Y when the format command prompted for (Y/N).
Check whether properties are properly set are not in core-site.xml and hdfs-site.xml
Then run the following command
$ hdfs namenode -format
Not sure but check the ownership of the namenode folder.
It should be hadoop user or associate user which has authority to access this folder.
I have the same issue and solved by chnaging the ownership of the folder. Also assign full permission to the folder.
Hope this helps.
my namenode is not starting up.
Tried formatting and deleting tmp directory before attempting a restart. but it doesn't come up.
Currently i am attemting for a two node cluster. I cloned both nodes from a single node machine. And changed properties to resemble one for name node, job tracker and secondary name node. And the other for the rest.
On trying to start the name node. I am getting below exception in logs. Tried searching, but didn't find anything specific to my problem. Also i have set up password less ssh, in case any permissions are denied beacause of that.

I think you are not giving the permissions for the namenode meta-data location correctly. To make sure it works correctly, Verify your procedure following the steps below.
Assuming Namenode meta-data location: /storage/name
mkdir -p /storage/name
chown -R hdfs:hadoop /storage/name
sudo -u hdfs hadoop namenode -format
service hdfs-namenode start (assuming cdh rpm installation is used. This varies with the installation method you used)
Hadoop daemon will start as an hdfs user, and if the metadata location permissions are not set to hadoop user and hadoop superuser group, you get the error mentioned above.
If you observe the above log generated, FileSystem owner: fsOwner is hdfs and super group is supergroup. And the Exception is FileNotFound because the service responsible to start namenode is unable to access the filesystem, since it does not have required permissions.
I had the same problem in hortonworks after adding another disk to hdfs. I simply did chown hdfs:hadoop -R /hadoop/hdfs and it started working.
For my hadoop on Unbutu(WSL), it works by typing in:
cd /usr/local/hadoop # your directory path may be different
./sbin/stop-dfs.sh # stop
rm -r ./tmp # delete tmp folder
./bin/hdfs namenode -format # reformat NameNode
./sbin/start-dfs.sh # restart
Hope this can help u :)
Much like states when I run the command sudo service hadoop-hdfs-namenode start the command failed with the below message.

The error itself is pretty self explanatory, the directory /var/lib/hadoop-hdfs/cache/hdfs/dfs/name is missing which is correct. The cache directory was empty so I created /cache/hdfs/dfs/name. I also changed the owner and group to match that of the directory above them. hdfs:hadoop.
I again run the format command sudo -u hdfs hdfs namenode –format which ends the same way as it did prior to creating this directory.

My system is running in VirtualBox with a CentOS 6.6 guest, Oracle JDK 1.7, and attempting to run Cloudera CDH4. Any input on what to do next to resolve this issue would be appreciated.
If you copy and paste the format command from slides or something, can you actually type it and see if it works?
I don't know if you can see the different between
–format and -format.
The dash looks different to me.
Had the same issue formatting the namenode. Retyped the commando (not copy-paste):
hdfs namenode -format
it worked. Thx https://stackoverflow.com/users/4533812/james
I am new to Hadoop and facing the following issue while starting NameNode with ./hadoop-daemon.sh start namenode command.
Steps I followed:
1. Downloaded Ubuntu13 VM ans installed Java 1.6 and hadoop-2.2.0
2. updated the configuration files
3. ran this hadoop namenode –format
4. ran this from sbin dir ./hadoop-daemon.sh start namenode
Error is:

Can someone help me to resolve this issue, I tried to google but still didn't find the solution.
Looks like your "hadoop namenode -format" didn't take (I assume you've tried hitting that command again and it still doesn't work). When you invoke hadoop namenode -format the user you are running as must have write access to the directories in dfs.data.dir and dfs.name.dir.
By default they are set to
${hadoop.tmp.dir}/dfs/data
and
${hadoop.tmp.dir}/dfs/name
where hadoop.tmp.dir is another config property that defaults to /tmp/hadoop-${username}.
So by default the hadoop data files are kept under your /tmp directory, which is not that great, especially if you have scripts that can clean out those directories.
Ensure that in core-site.xml you have set your dfs.data.dir and dfs.name.dir to directories that the user who is running hadoop admin commands and starting the hadoop daemons can write to. Then reformat HDFS and try again.
