liuxian updated HADOOP-14358:
-----------------------------
    Description: 
I am not sure whether this is a problem, in the "public final class NativeCodeLoader,  when
"loadLibrary("hadoop")",  encounter this Exception. This time I want to confirm whether nativeCodeLoaded
variables should be true

Log print as follows:

native-hadoop library...
