Examples of HadoopAccessorService

org.apache.oozie.service.HadoopAccessorService
The HadoopAccessorService returns HadoopAccessor instances configured to work on behalf of a user-group.
The default accessor used is the base accessor which just injects the UGI into the configuration instance used to create/obtain JobClient and ileSystem instances.
The HadoopAccess class to use can be configured in the oozie-site.xml using the oozie.service.HadoopAccessorService.accessor.class property.

            URI uri = new URI(appPath);
            LOG.debug("user =" + user);
            HadoopAccessorService has = Services.get().get(HadoopAccessorService.class);
            Configuration fsConf = has.createJobConf(uri.getAuthority());
