I was following the Hadoop 0.17.0 quickstart guide (Windows and Cygwin). First of all:
1)in C:\cygwin\home\bstarchev change hadoop-env.sh and copy in C:\hadoop-0.17.0\conf echo 'export JAVA_HOME=/cygdrive/c/"Program Files"/Java/jdk1.5.0_12' >> hadoop-env.sh 2)in C:\cygwin\home\bstarchev create hadoop-site.xml and copy in C:\hadoop-0.17.0\conf echo '<?xml version="1.0"?>' > hadoop-site.xml echo '<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>' >> hadoop-site.xml echo '<!-- Put site-specific property overrides in this file. -->' >> hadoop-site.xml echo " <configuration>" >> hadoop-site.xml echo " <property>" >> hadoop-site.xml echo " <name>fs.default.name</name>" >> hadoop-site.xml echo " <value>localhost:9000</value>" >> hadoop-site.xml echo " </property>" >> hadoop-site.xml echo " <property>" >> hadoop-site.xml echo " <name>mapred.job.tracker</name>" >> hadoop-site.xml echo " <value>localhost:9001</value>" >> hadoop-site.xml echo " </property>" >> hadoop-site.xml echo " <property>" >> hadoop-site.xml echo " <name>dfs.replication</name>" >> hadoop-site.xml echo " <value>1</value>" >> hadoop-site.xml echo " </property>" >> hadoop-site.xml echo " </configuration>" >> hadoop-site.xml 3) [EMAIL PROTECTED] ~ $ cd /cygdrive/c/hadoop-0.17.0 [EMAIL PROTECTED] /cygdrive/c/hadoop-0.17.0 $ bin/hadoop namenode -format 08/07/09 13:22:51 INFO dfs.NameNode: STARTUP_MSG: /************************************************************ STARTUP_MSG: Starting NameNode STARTUP_MSG: host = bis-laptop/192.168.85.56 STARTUP_MSG: args = [-format] STARTUP_MSG: version = 0.17.0 STARTUP_MSG: build = http://svn.apache.org/repos/asf/hadoop/core/branches/bran ch-0.17 -r 656523; compiled by 'hadoopqa' on Thu May 15 07:22:55 UTC 2008 ************************************************************/ 08/07/09 13:22:53 INFO fs.FSNamesystem: fsOwner=bstarchev,None,root,Administrato rs,Users,SophosUser 08/07/09 13:22:53 INFO fs.FSNamesystem: supergroup=supergroup 08/07/09 13:22:53 INFO fs.FSNamesystem: isPermissionEnabled=true 08/07/09 13:22:53 INFO dfs.Storage: Storage directory \tmp\hadoop-bstarchev\dfs\ name has been successfully formatted. 08/07/09 13:22:53 INFO dfs.NameNode: SHUTDOWN_MSG: /************************************************************ SHUTDOWN_MSG: Shutting down NameNode at bis-laptop/192.168.85.56 ************************************************************/ [EMAIL PROTECTED] /cygdrive/c/hadoop-0.17.0 $ bin/start-all.sh starting namenode, logging to /cygdrive/c/hadoop-0.17.0/bin/../logs/hadoop-bstar chev-namenode-bis-laptop.out : no address associated with name localhost : no address associated with name localhost starting jobtracker, logging to /cygdrive/c/hadoop-0.17.0/bin/../logs/hadoop-bst archev-jobtracker-bis-laptop.out : no address associated with name localhost [EMAIL PROTECTED] /cygdrive/c/hadoop-0.17.0 $ bin/hadoop dfs -put conf input 08/07/09 13:27:16 WARN fs.FileSystem: "localhost:9000" is a deprecated filesyste m name.
