Java HotSpot(TM) 64-Bit Server VM warning: You have loaded library
/usr/local/hadoop/lib/native/libhadoop.so.1.0.0 which might have disabled stack
guard. The VM will try to fix the stack guard now.
It's highly recommended that you fix the library with 'execstack -c <libfile>',
or link it with '-z noexecstack'.
