Hi Neeraj,
This error doesn't look to be kerberos related initially. Can you
verify if 192.168.49.51
has the tasktracker process running?

Hi Geelong,
What's the ownership and permissions on /usr/hadoop/tmp/dfs/data? If I
recall correctly, I believe it should be hdfs:hadoop, where the owner has
full permissions and the group can read and execute. Does /var/log for the
datanode show any errors?

Hi Savitha,
On your nodes running tasktrackers and datanodes, there is a core-site.xml
file that specifies the namenode to contact via the property fs.default.name.
In addition, there is a mapred-site.xml which specifies address of
jobtracker.
I hope that helps.

Robert

Hi Dhanasekaran,
I believe you are trying to ask if it is recommended to use the
decommissioning feature to remove datanodes from your cluster, the answer
would be yes. As far as how to do it, there should be some information
here http://wiki.apache.org/hadoop/FAQ that should help.

Hi Vikas,
This is showing the total amount of memory currently used in the Java
virtual machine for the namenode process versus the maximum amount of
memory that the Java virtual machine will attempt to use for the namenode
process.
I hope that helps.

Hi Shagun,
You may want to verify if all the services are running. Try running jps to
get list of java processes. Ideally, if all is well you should see the
following processes if running on a single node setup :
NameNode
TaskTracker
SecondaryNamenode
JobTracker
DataNode
Hope that helps.

Hi Ivan,
Regarding the mapreduce.jobtracker.retiredjobs.cache.size property, the
jobtracker keeps information about a number of completed jobs in memory.
There's a threshold for this, which is a single day by default - as well as
a certain number of jobs per user. Once these limits are hit, the job
Hi James,
This should be fine, but just wanted to add that you will need to also make
the change on your other nodes within the cluster, so they know how to
contact the filesystem.

Do you simply want to schedule the job to run at specific times? If so, I

Hi Jean,
Hadoop will not factor in number of disks or directories, but rather mainly
allocated free space. Hadoop will do its best to spread the data across
evenly amongst the nodes. For instance, let's say you had 3 datanodes

Sorry overlooked that you were running Teragen which doesn't execute a
shuffle, hence it's not getting the error. So initial thoughts of issue
being specific to mapreduce program shouldn't be the case.

Is your namenode up and running? Also, you can try checking the job

To help isolate, what happens if you run a different job? Also, if you

I believe not many folks have deployed it. Although some testing has been
done it may not be stable. If you are really stuck on using that release,
you can check on the release notes and bugs filed for that version to see
if there are any potential show stoppers for you. As always, test as much
