> Currently, Hadoop code can discover custom implementations of {{FileSystem}} via either
configuration mapping the scheme to the class name or the Java {{ServiceLoader}} mechanism.
 However, for implementations of {{AbstractFileSystem}}, only configuration is supported and
not the {{ServiceLoader}} mechanism.  Because of this, we must either specify the classes
in core-default.xml (which is somewhat unusual because the class is likely to be in a hadoop-tools
module instead of hadoop-common) or ask users to set it in core-site.xml at deployment time.
 This issue proposes to implement the {{ServiceLoader}} mechanism for {{AbstractFileSystem}}.
