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. -->*
*<configuration>*

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
deprecated filesystem name. Use "hdfs://134.130.223.85:9000/" instead.*

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
