Subject NoClassDefFoundError running under Cygwin on Windows Server 2003
Date Thu, 26 Apr 2007 09:21:41 GMT
I've been trying to get Hadoop running under Cygwin on Windows Server
2003, using the Sun JDK.

Steps I had to take so far...

Dos2unix on all of the shell scripts, this may be down to the unzip on
my machine This solves the error:
	bin/hadoop: line 18: $'\r': command not found

Then I removed spaces from paths, as some of the scripts don't quote
paths. I saw this in the Jira already.

Now I'm stuck on:

	$ bin/hadoop dfs -ls
	Exception in thread "main" java.lang.NoClassDefFoundError:

This seems to come from org.apache.hadoop.util.PlatformName

	$ java -cp hadoop-0.12.3-core.jar
	Windows 2003-x86-32

Which is used by bin/hadoop at line 134:


Given that the error is the latter part of the PlatformName, following
the space it appears to be a quoting problem, so suggestions of how to
fix that would be helpful, but I'm also confused as the JAVA_PLATFORM is
then used to create [paths to native libraries:

	$ grep -n JAVA_PLATFORM bin/hadoop

My distro, taken from
http://www.apache.org/dyn/closer.cgi/lucene/hadoop/ doesn't contain a
build/native folder and ${HADOOP_HOME}/lib/native only contains a build
for Linux-i386-32.

Can anyone spot the obvious build/install step that I've missed, or
point me at relevant documentation? I searched the wiki and google-brain
