> Several changes for Falcon Atlas integration.
> In Falcon's params_linux.py for HDP 2.5, set atlas_hook_cp even if Atlas is
> not present on this host since the RPM will install the dependency if Falcon
> is installed.
> {code}
> atlas_hook_cp = ""
> if has_atlas_in_cluster():
> atlas_hook_filename =
> default('/configurations/atlas-env/metadata_conf_file',
> 'atlas-application.properties')
> # Only append /etc/atlas/conf to classpath if on HDP 2.4.* and atlas server
> is running on this host.
> if has_atlas_server_on_host and
> check_stack_feature(StackFeature.ATLAS_CONF_DIR_IN_PATH,
> stack_version_formatted):
> atlas_conf_dir = os.environ['METADATA_CONF'] if 'METADATA_CONF' in
> os.environ else format('{stack_root}/current/atlas-server/conf')
> atlas_home_dir = os.environ['METADATA_HOME_DIR'] if 'METADATA_HOME_DIR'
> in os.environ else format('{stack_root}/current/atlas-server')
> atlas_hook_cp = atlas_conf_dir + os.pathsep +
> os.path.join(atlas_home_dir, "hook", "falcon", "*") + os.pathsep
> #endregion
> {code}
> Further, Stack Advisor in HDP 2.5, plus EU/RU to HDP 2.5 needs to change
> Falcon's falcon-startup.properties "*.application.services" to use
> "org.apache.atlas.falcon.service.AtlasService" instead of
> "org.apache.falcon.atlas.service.AtlasService" since the class was renamed.
