Vinod Kumar Vavilapalli commented on YARN-2571:
-----------------------------------------------
Apologies for coming in really late on this.
bq. startup: create the /services and /users paths with system ACLs (yarn, hdfs
principals)
bq. app-launch: create the user directory /users/$username with the relevant
permissions (CRD) for them to create subnodes.
None of this is RM responsibility. Similar to creation of user directories on
HDFS, this needs to be taken care of by administrators/external systems.
bq. bq. attempt, container, app completion: remove service records with the
matching persistence and ID
This looks like application-level responsibility. Removing records on
container-completion can and should be done by the individual apps'
ApplicationMasters. Removing records on app completion should be done in an
application-cleanup container (YARN-2261). Any use-case for application-attempt
level records?

> The RM needs to (optionally) integrate with the YARN registry:
> # startup: create the /services and /users paths with system ACLs (yarn, hdfs
> principals)
> # app-launch: create the user directory /users/$username with the relevant
> permissions (CRD) for them to create subnodes.
> # attempt, container, app completion: remove service records with the
