Description

In FileSystemInputPartition, we check whether the copy to local succeeded by checking whether the file exists locally:

                _fileSystem.CopyToLocal(sourceUri, localFilePath);
                if (File.Exists(localFilePath))
                {
                    Logger.Log(Level.Info, string.Format
                        (CultureInfo.CurrentCulture, "File {0} is Copied to local {1}.", sourceUri, localFilePath));
                }
                else
                {
                    string msg = string.Format
                        (CultureInfo.CurrentCulture, "File {0} is NOT Copied to local {1}.", sourceUri, localFilePath);
                    Exceptions.Throw(new FileLoadException(), msg, Logger);
                }

However, the FileLoadException doesn't contain any useful error message. We should fix that.
