Subject RE: problem with running WordCode v0 with a distributed operation
Date Tue, 30 Jun 2009 15:30:31 GMT
Hello,

I suggest that you check iptables on your systems.  At one time, one of
my nodes showed a similar error, and this was the culprit.

Good luck,

Danny

Subject: problem with running WordCode v0 with a distributed operation

Help help help,

 I am a new user, it has been already 2-3 weeks that I am trying to run
Hadoop 0.18.3.


 *My settings:*

   1.

   I am on LINUX
   2.

   Using the Java 1.6.0
   3.

   I have unpacked the hadoop-0.18.3 folder directly on the desktop


*Working steps:*

   1.

   I have succeeded to run it on the local
   2.

   I went through the quick start tutorial and managed to operate

   Hadoop in the standalone and the Pseudo-distributed motes
   3.

   I started going through the map/reduce tutorial and managed to

   run the WordCount v1.0 with a standalone operation.

*Current status:*

   1.

   I would like to run the WordCount v1.0 example on a distributed
operation
   2.

   I went through the steps in the cluster setup tutorial and did the
   following:


   -

   On a distant server I am running 4 virtual machines:

   134.130.223.58:1

   134.130.223.72:1

   134.130.223.85:1

   134.130.223.92:1
   -

   My own machine has the following ip address

   134.130.222.54
   -

   The hadoop-en.sh file is the same on all the five machines:

   *export HADOOP_HEAPSIZE=500*

   *export JAVA_HOME="/usr/java/jdk1.6.0_14"*

   *export HADOOP_NAMENODE_OPTS="-Dcom.sun.management.jmxremote
   $HADOOP_NAMENODE_OPTS"*

   *export HADOOP_SECONDARYNAMENODE_OPTS="-Dcom.sun.management.jmxremote
   $HADOOP_SECONDARYNAMENODE_OPTS"*

   *export HADOOP_DATANODE_OPTS="-Dcom.sun.management.jmxremote *

   *$HADOOP_DATANODE_OPTS"*

   *export HADOOP_BALANCER_OPTS="-Dcom.sun.management.jmxremote *

   *$HADOOP_BALANCER_OPTS"*

   *export HADOOP_JOBTRACKER_OPTS="-Dcom.sun.management.jmxremote *

   *$HADOOP_JOBTRACKER_OPTS"*

   *export HADOOP_HOME="/root/Desktop/hadoop-0.18.3"*

   *export HADOOP_VERSION="0.18.3"*

   *export HADOOP_LOG_DIR=${HADOOP_HOME}/logs*
   -

   The hadoop-site.xml is the same on all the five machines:

   *<?xml version="1.0"?>*

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

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

   The slaves file is the same on all five machines and contains:

   134.130.223.72

   134.130.222.54

   134.130.223.92
   -

   from the Namenode machine 134.130.223.85 I have formatted a new
namenode,
   started the hdfs (bin/start-dfs.sh) and started the Map-reduce
   (bin/start-mapred.sh)


 *Problem:*

Si      Since the jar file of the WordCount was already created (by the
local operation) in the folder

us     usr/tina, I tried running directly the application similarly to
local
operation by typing

   *$bin/hadoop jar usr/tina/wordcount.jar org.myorg.WordCount
usr/tina/wordcount/input usr/tina/wordcount/output.*

  Then I got the following error:



 *09/06/29 19:38:05 WARN fs.FileSystem: "134.130.223.85:9000" is a

 * Questions*

   1.

   Can someone help me in solving/debugging this problem?

   P.S: I have tried to stop the HDFS with bin/stop-dfs.sh before

   starting new ones.


 Thank you,

C.J
