> It looks like cassandra.utils.CLibrary.createHardLinkWithExec() does not
> check for any errors in the execution of the hard-link-making utility. This
> could be bad if, for example, the user has put the snapshot directory on a
> different filesystem from the data directory. The hard linking would fail and
> the sstable snapshots would not exist, but no error would be reported.
> It does look like errors with the more direct JNA link() call are handled
> correctly- an exception is thrown. The WithExec version should probably do
> the same thing.
> Definitely it would be enough to check the process exit value from /bin/ln
> for nonzero in the *nix case, but I don't know whether 'fsutil hardlink
> create' or 'cmd /c mklink /H' return nonzero on failure.
> For bonus points, use any output from the Process's error stream in the text
> of the exception, to aid in debugging problems.
