> My Hadoop installation is  having trouble loading the native code library. It appears
from the log below that java.library.path is missing the basedir in its path. The libraries
are built, and present in the directory shown below (relative to hadoop-common directory).
Instead of seeing:
>  /build/native/Linux-amd64-64/lib
> I would expect to see:
>  /path/to/hadoop-common/build/native/Linux-amd64-64/lib
> I'm working in branch-0.22.
> 2011-01-10 17:09:27,695 DEBUG org.apache.hadoop.util.NativeCodeLoader: Failed to load
native-hadoop with error: java.lang.UnsatisfiedLinkError: no hadoop in java.library.path
> 2011-01-10 17:09:27,695 DEBUG org.apache.hadoop.util.NativeCodeLoader: java.library.path=/build/native/Linux-amd64-64/lib
> 2011-01-10 17:09:27,695 WARN org.apache.hadoop.util.NativeCodeLoader: Unable to load
native-hadoop library for your platform... using builtin-java classes where applicable
