Would it work if you package your native library under the directory
of lib/native/<arch>/...?

Hi Stuart,
Hadoop itself doesn't have any nice way of dealing with this that I
know of.
I think your best bet is to do something like:
String dataModel = System.getProperty("sun.arch.data.model");
if ("32".equals(dataModel)) {
System.loadLibrary("mylib_32bit");
} elseif ("64".equals(dataModel)) {
System.loadLibrary("mylib_64bit");
} else {
throw new RuntimeException("Unknown data model: " +
String.valueOf(dataModel));
}
Then include your libraries as libmylib_32bit.so and
libmylib_64bit.so in
the distributed cache.
Hope that helps

My hadoop cluster is a combination of i386-32bit and amd64-64bit
machines.
I have some native code that I need to execute from my mapper. I
have
different native libraries for the different architectures.
How can I accomplish this? I've looked at using -files or
DistributedCache
to push the native libraries to the nodes, but I can't figure out
how to
make sure I link against the correct native library (for the
architecture
the map task is running on).
Anyone else run into this? Any suggestions?
