Hi all,

I just installed Hadoop(single node cluster) and tried to start and stop the
nodes , and it said
no jobtracker to stop , no namenode to stop

however the tutorial i used suggest that jobtracker and namenodes should
also have started ? Why does this happen?
am i missing something?

http://www.michael-noll.com/wiki/Running_Hadoop_On_Ubuntu_Linux_(Single-Node_Cluster)
hadoop@pdhanapa-laptop:/home/pdhanapa/Desktop/hadoop/bin$ jps
20671 Jps
20368 DataNode
20463 SecondaryNameNode

hadoop@pdhanapa-laptop:/home/pdhanapa/Desktop/hadoop/bin$ ./stop-all.sh
no jobtracker to stop
localhost: no tasktracker to stop
no namenode to stop
localhost: stopping datanode
localhost: stopping secondarynamenode

I am facing the same problem I look in the log files I find this that error

FATAL org.apache.hadoop.mapred.JobTracker: java.net.BindException:
Problem binding to cannonau.isti.cnr.it/146.48.82.190:9001 : Address already
in use

I also did a netstat to see whether the port is in use but it does not show
that the port is in use I also changed the port and did another netstat and
the error is the same
any ideas ? please help
when i stop hadoop here is what i get  there is no namenode to stop and
there is no job tracker
ahmednagy@cannonau:~/HadoopStandalone/hadoop-0.21.0/bin$ ./stop-all.sh
This script is Deprecated. Instead use stop-dfs.sh and stop-mapred.sh
no namenode to stop

look at the logs of job tracker, maybe you will get some clues.

The issue here is that these resources failed to start. What happens
here is as soon as the java process is started the system returns an
ok status to the script. However the processes die moments later as
they start up.

For example if you start the namenode, script returns ok, namenode
runs and realizes its dfs.name directory is not formatted. Then it
stops.

Generally after starting a hadoop process, tail the log it creates for
a few seconds and make sure it REALLY starts up. Really the scripts
should do more pre-startup checking, but the scripts could not test
for every possible condition that could cause hadoop not to start.

Also for long running deamons the pid files are written to /tmp see
bin/hadoop-daemon.sh
If something is cleaning /tmp stop arguments are unable to find the pid.

That is shell scripting for you :)

Hi Prabhu,

I am facing exactly the same problem. I too followed the steps in the below
link.

Please let me know which configuration file was modified and what were the
changes.

Thanks,

Hi Madhu,

Thanks for the response, sorry was busy couldn't check.

My mapred-site.xml is as follows.

Let me know the suggested changes to be done.

THanks in advance.

<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>

<!-- Put site-specific property overrides in this file. -->

<!-- In: conf/mapred-site.xml -->
<configuration>
<property>
  <name>mapred.job.tracker</name>
  <value>localhost:54311</value>
  <description>The host and port that the MapReduce job tracker runs
  at.  If "local", then jobs are run in-process as a single map
  and reduce task.
  </description>
</property>
</configuration>

Hi Prabhu,

I am facing exactly the same problem. I too followed the steps in the below
link.

http://www.michael-noll.com/tutorials/running-hadoop-on-ubuntu-linux-single-node-cluster/

Please let me know which configuration file was modified and what were the
changes.

Thanks,
Balaji
