>
> 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}}.
