As I can read in the doc Windows is supported as a dev platform within the use of cygwin (but I've will not have pain if I've to switch to linux! :):
thx Pre-requisites Supported Platforms - GNU/Linux is supported as a development and production platform. Hadoop has been demonstrated on GNU/Linux clusters with 2000 nodes. - Win32 is supported as a *development platform*. Distributed operation has not been well tested on Win32, so it is not supported as a *production platform*. 2009/6/11 Nick Cen <[email protected]> > as far as i know, hadoop has not been ported to the windows. > > 2009/6/11 Alexandre Jaquet <[email protected]> > > > Hello, > > > > For my first try I will use windows as a non clustered system. > > > > I'm been trying to run it after the setting up of the JAVA_HOME env > > variable > > > > but when I run the following command *bin/hadoop jar > hadoop-*-examples.jar > > grep input output 'dfs[a-z.]+' I'm getting > > this : > > * > > > > *$ bin/hadoop jar hadoop-*-examples.jar grep input output 'dfs[a-z.]+' > > /cygdrive/c/Documents and Settings/Alexandre Jaquet/Mes > > documents/hadoop-0.20.0/ > > hadoop-0.20.0/bin/../conf/hadoop-env.sh: line 2: $'\r': command not found > > /cygdrive/c/Documents and Settings/Alexandre Jaquet/Mes > > documents/hadoop-0.20.0/ > > hadoop-0.20.0/bin/../conf/hadoop-env.sh: line 7: $'\r': command not found > > /cygdrive/c/Documents and Settings/Alexandre Jaquet/Mes > > documents/hadoop-0.20.0/ > > hadoop-0.20.0/bin/../conf/hadoop-env.sh: line 9: export: > > `Files/Java/jdk1.6.0_12 > > ': not a valid identifier > > /cygdrive/c/Documents and Settings/Alexandre Jaquet/Mes > > documents/hadoop-0.20.0/ > > hadoop-0.20.0/bin/../conf/hadoop-env.sh: line 10: $'\r': command not > found > > /cygdrive/c/Documents and Settings/Alexandre Jaquet/Mes > > documents/hadoop-0.20.0/ > > hadoop-0.20.0/bin/../conf/hadoop-env.sh: line 13: $'\r': command not > found > > /cygdrive/c/Documents and Settings/Alexandre Jaquet/Mes > > documents/hadoop-0.20.0/ > > hadoop-0.20.0/bin/../conf/hadoop-env.sh: line 16: $'\r': command not > found > > /cygdrive/c/Documents and Settings/Alexandre Jaquet/Mes > > documents/hadoop-0.20.0/ > > hadoop-0.20.0/bin/../conf/hadoop-env.sh: line 19: $'\r': command not > found > > /cygdrive/c/Documents and Settings/Alexandre Jaquet/Mes > > documents/hadoop-0.20.0/ > > hadoop-0.20.0/bin/../conf/hadoop-env.sh: line 29: $'\r': command not > found > > /cygdrive/c/Documents and Settings/Alexandre Jaquet/Mes > > documents/hadoop-0.20.0/ > > hadoop-0.20.0/bin/../conf/hadoop-env.sh: line 32: $'\r': command not > found > > /cygdrive/c/Documents and Settings/Alexandre Jaquet/Mes > > documents/hadoop-0.20.0/ > > hadoop-0.20.0/bin/../conf/hadoop-env.sh: line 35: $'\r': command not > found > > /cygdrive/c/Documents and Settings/Alexandre Jaquet/Mes > > documents/hadoop-0.20.0/ > > hadoop-0.20.0/bin/../conf/hadoop-env.sh: line 38: $'\r': command not > found > > /cygdrive/c/Documents and Settings/Alexandre Jaquet/Mes > > documents/hadoop-0.20.0/ > > hadoop-0.20.0/bin/../conf/hadoop-env.sh: line 41: $'\r': command not > found > > /cygdrive/c/Documents and Settings/Alexandre Jaquet/Mes > > documents/hadoop-0.20.0/ > > hadoop-0.20.0/bin/../conf/hadoop-env.sh: line 46: $'\r': command not > found > > /cygdrive/c/Documents and Settings/Alexandre Jaquet/Mes > > documents/hadoop-0.20.0/ > > hadoop-0.20.0/bin/../conf/hadoop-env.sh: line 49: $'\r': command not > found > > /cygdrive/c/Documents and Settings/Alexandre Jaquet/Mes > > documents/hadoop-0.20.0/ > > hadoop-0.20.0/bin/../conf/hadoop-env.sh: line 52: $'\r': command not > found > > bin/hadoop: line 258: C:/Program/bin/java: No such file or directory > > bin/hadoop: line 289: C:/Program/bin/java: No such file or directory > > bin/hadoop: line 289: exec: C:/Program/bin/java: cannot execute: No such > > file or > > directory* > > > > Here is my *hadoop-env.sh > > > > # Set Hadoop-specific environment variables here. > > > > # The only required environment variable is JAVA_HOME.
