Description

Thus says Brian Whitman in NUTCH-432:

"In some later nightly in the past few weeks (not sure when) the bin/nutch script stopped working on my Macs with
Exception in thread "main" java.lang.NoClassDefFoundError: OS
On any command. I tracked it down to the JAVA_PLATFORM env variable that is used to try to find a native hadoop library. The line
JAVA_PLATFORM=`CLASSPATH=${CLASSPATH} ${JAVA} org.apache.hadoop.util.PlatformName`
in bin/nutch returns "Mac OS X-ppc-32", which then appears as
-Djava.library.path=/Users/bwhitman/Desktop/nn/lib/native/Mac OS X-ppc-32
in the java command line to start a nutch tool.
Not sure the best way to fix this, but I manually put
JAVA_PLATFORM='MacOSX/PPC'
and the error went away. "

The same problem occurs in bin/hadoop.

I propose the following fix:

JAVA_PLATFORM=`CLASSPATH=${CLASSPATH} ${JAVA} org.apache.hadoop.util.PlatformName | sed -e 's/ /_/g'`

The alternative would be to fix this in PlatformName, but then we may want to get the real platform name in some other places. We could also add a cmd-line switch to PlatformName.
