Aaron T. Myers commented on HADOOP-8884:
----------------------------------------

The test failure is spurious and unrelated, so don't worry about that.

I agree with Suresh's suggestion of making the log one line, except that I 
recommend you pass the Throwable as the second argument to LOG.warn, so that 
the full stack trace is printed, i.e.:

{code}
LOG.warn("Continuing after failing to load native-hadoop - java.library.path=" +
    System.getProperty("java.library.path") + " with error:", t);
{code}
                
> DEBUG should be WARN for DEBUG util.NativeCodeLoader: Failed to load 
> native-hadoop with error: java.lang.UnsatisfiedLinkError
