Description

I recently tried out 2.1.0 beta in the hope of benefiting from numerous improvements made re: running on cygwin. I cannot even get a "bin/hadoop version" to work, it gets a java.lang.NoClassDefFoundError for the common classes such as org.apache.hadoop.util.VersionInfo

I've looked a similiar bug report and have made sure that HADOOP_PREFIX is set, and that HADOOP_HOME is not set. I've looked at the output of "bin/hadoop classpath" and it looks correct EXCEPT that 2.1.0 shows the classpath using unix syntax and paths, while my older version of hadoop (1.2.1) shows it using Windows syntax and paths.
