"C:/Program: No such file or directory" error when running jars in the hadoop folder

[Panagiotis Kalogeropoulos]

I am trying to run hadoop (version 1.1.1) in Windows 7, but when I try to execute some of the jars (like the hadoop-examples-1.1.1.jar or hadoop-test-1.1.1.jar) I get the following error:
bin/hadoop: line 320: C:/Program: No such file or directory

The thing is that the jars are executing without any serious problem. For instance, this is what is shown when I execute the hadoop-examples-1.1.1.jar :

$ bin/hadoop jar hadoop-examples-1.1.1.jar
bin/hadoop: line 320: C:/Program: No such file or directory
An example program must be given as the first argument.
Valid program names are:
aggregatewordcount: An Aggregate based map/reduce program that counts the words in the input files.
aggregatewordhist: An Aggregate based map/reduce program that computes the histogram of the words in the input files.
dbcount: An example job that count the pageview counts from a database.
grep: A map/reduce program that counts the matches of a regex in the input.
join: A job that effects a join over sorted, equally partitioned datasets
multifilewc: A job that counts words from several files.
pentomino: A map/reduce tile laying program to find solutions to pentomino problems.
pi: A map/reduce program that estimates Pi using monte-carlo method.
randomtextwriter: A map/reduce program that writes 10GB of random textual data per node.
randomwriter: A map/reduce program that writes 10GB of random data per node.
secondarysort: An example defining a secondary sort to the reduce.
sleep: A job that sleeps at each map and reduce task.
sort: A map/reduce program that sorts the data written by the random writer.
sudoku: A sudoku solver.
teragen: Generate data for the terasort
terasort: Run the terasort
teravalidate: Checking results of terasort
wordcount: A map/reduce program that counts the words in the input files.


As you can see it shows correctly all available example programs. Has anyone seen something similar?

I didn't know you could run Hadoop directly on Windows - I thought you needed to use Cygwin or a Linux VM etc. This looks like it might be a problem with the Windows file path. Check if there's a path like "C:/Program Files/..." in there somewhere that isn't being quoted properly, so Hadoop thinks it's supposed to look in "C:/Program/" instead?

Yes, I am using Cygwin so that I can run the Linux commands. I mentioned only Windows 7 just to tell you under which os I am trying to run hadoop. Indeed, there seems to be some problem with the Windows Classpath. As we can see, the line 320 in the bin/hadoop file is
JAVA_PLATFORM=`CLASSPATH=${CLASSPATH} ${JAVA} -Xmx32m ${HADOOP_JAVA_PLATFORM_OPTS} org.apache.hadoop.util.PlatformName | sed -e "s/ /_/g"`

The thing is that even after I quote the CLASSPATH and JAVA_HOME variables, I get the same message. And what surprises me even more is that the jars are executing correctly. Maybe there is something wrong with the version that I am working? I will try with version 0.22.0 and see how it goes.
