Subject Re: java.lang.UnsatisfiedLinkError - Unable to load libGfarmFSNative library
Date Thu, 27 Jun 2013 02:55:40 GMT
>From the log:  libGfarmFSNative.so: libgfarm.so.1: cannot open shared
object file: No such file or directory

I don't think you put libgfarm.* under
$HADOOP_HOME/lib/native/Linux-amd64-64 (Linux-i386-32 if running on 32 bits
OS) on all nodes.
