Wangda Tan commented on YARN-8902:
----------------------------------
Thanks [~cheersyang] , a couple of high-level questions and miscs:
CsiAdaptorClient is not implemented, does this patch works end to end?
How to handle client ask volumes for every allocate request (let's say same
volume id)? What will the expectation be for users, should they expect failures
for the allocate() call or duplicated volume id will be simply ignored?
How to handle RM recovery case for volumes, are we going to recover volume
states? or do we need to do that?
*Miscs:*
- org.apache.hadoop.yarn.server.resourcemanager.volume => ..rmvolume?
> Add volume manager that manages CSI volume lifecycle
