Eric Yang updated YARN-7605:
----------------------------
Attachment: YARN-7605.015.patch
- Added a fix to display remaining lifetime properly.
Patch 015 is still returning full spec + status instead of partial status for
stopped or initializing applications. My recommendation is to return full spec
because REST API does not provide other end point to retrieve spec. If we want
to build UI on top, full spec information is required. Performance improvement
can be implemented in future release where we cache the spec object in Solr or
HBase. Those ideas are beyond the scope of this JIRA.

> In YARN-7540, all client entry points for API service is centralized to use
> REST API instead of having direct file system and resource manager rpc calls.
> This change helped to centralize yarn metadata to be owned by yarn user
> instead of crawling through every user's home directory to find metadata.
> The next step is to make sure "doAs" calls work properly for API Service.
> The metadata is stored by YARN user, but the actual workload still need to be
> performed as end users, hence API service must authenticate end user kerberos
> credential, and perform doAs call when requesting containers via
> ServiceClient.
