Hello,
I'm trying to get Hadoop working on Cygwin/Windows XP in
Pseudo-Distributed Mode. I downloaded version 0.21.0 and unpacked it
to a cygwin directory. I'm following the quickstart directions here:
http://hadoop.apache.org/common/docs/r0.20.2/quickstart.html
I get the following error when I try to check the Hadoop version:
$ bin/hadoop --version
Exception in thread "main" java.lang.NoClassDefFoundError:
org/apache/hadoop/util/PlatformName
Caused by: java.lang.ClassNotFoundException: org.apache.hadoop.util.PlatformName
at java.net.URLClassLoader$1.run(URLClassLoader.java:202)

at java.lang.ClassLoader.loadClass(ClassLoader.java:307)
at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301)
at java.lang.ClassLoader.loadClass(ClassLoader.java:248)
Could not find the main class: org.apache.hadoop.util.PlatformName. Program wil
l exit.
Unrecognized option: --version
Could not create the Java virtual machine.
I get similar exceptions when I run "start-all.sh", but I am still
able to browse the web interface for NameNode and JobTracker.
I'm sure has something to do with an installation step that I'm
missing--some step that windows users have to do, that linux users do
not. I did web searches for this problem, but I only found it
occurring when people were building Hadoop. I'm not building.
I appreciate any help anyone can give.
Thanks,
Chris
