DN logs backtrace when running under jsvc and /jmx is loaded

      Description

      Running the data node under jsvc and requesting /jmx falls victim to a kernel bug http://marc.info/?l=linux-kernel&m=133788505209725&w=2 which results in EACCES when open()ing /proc/self/fd to attempt to count the open filedescriptors.

      Hopefully someday we will have kernels with this bug fixed; in the meantime, the log spew which results is unpleasant:

        Robert,

        Thanks for offering to commit the patch! I've reuploaded it with the license grant checked.

        Also, just to be completely clear – the TestViewFsTrash regression does not appear to be related to my patch; and I didn't add a regression test due to the difficulty of testing a kernel-dependent failure.

        With this proposed fix, the JMX json contains the following:

        ...
            "MaxFileDescriptorCount" : 32768,
            "OpenFileDescriptorCount" : null,
        ...
        

        I'm not completely sure that "null" appearing here is kosher. Any feedback appreciated.
