Eric Yang commented on YARN-7799:
---------------------------------
[~billie.rinaldi] The summary of our discussion:
1. We can check prefix directory of yarn.service.framework.path to ensure all
sub-directories are world readable and executable to ensure other user can
access this path.
2. If the calling user to -enableFastLaunch is one of yarn.admin.acl, and
yarn.service.framework.path is pre-conigured. User is allowed to upload
service-dep.tar.gz.
3. If the calling user is dfs.cluster.administrators, user is allowed to
upload service-dep.tar.gz.
4. Auto-upload follows the same logic.

> As per [~jianhe] these are some followup items that make sense to do after
> YARN-7766. Quoting Jian's comment below -
> Currently, if user doesn't supply location when run yarn app
> -enableFastLaunch, the jars will be put under this location
> {code}
> hdfs:///yarn-services/<versionId>/service-dep.tar.gz
> {code}
> Since API server is embedded in RM, should RM look for this location too if
> "yarn.service.framework.path" is not specified ?
> And if "yarn.service.framework.path" is not specified and still the file
> doesn't exist at above default location, I think RM can try to upload the
> jars to above default location instead, currently RM is uploading the jars to
> the location defined by below code. This folder is per app and also
> inconsistent with CLI location.
> {code}
> protected Path addJarResource(String serviceName,
> Map<String, LocalResource> localResources)
> throws IOException, SliderException {
> Path libPath = fs.buildClusterDirPath(serviceName);
> {code}
> By doing this, the next time a submission request comes, RM doesn't need to
> upload the jars again.
