Hi Arun, Thanks for the prompt reply. I am not sure, I understood you correctly. Compile/binary/tar of what? The native files? The lib/native/Linux-amd64-64/ contains following files: libhadoop.a libhadoop.la libhadoop.so libhadoop.so.1 libhadoop.so.1.0.0
This directory is present in the package itself. So, should I make a tar of it and then provide it? I tried the following, but it failed: ant -Dcompile.native=true $HADOOP_HOME/lib/native/Linux-amd64-64/libhadoop.so The error I got is - "Target lib/native/Linux-amd64-64/libhadoop.so does not exist in the project Hadoop". Thanks, Aastha.
