IMPALA-8092: Add an admission controller debug page
This patch adds a new debug page "admission" that provides the
following details about resource pools:
- Pool configuration
- Relevant pool stats
- Queued Queries in order of being queued (local to the coordinator)
- Running Queries (local to this coordinator)
- Histogram of the distribution of peak memory used by queries admitted
to the pool
The aforementioned details can also be viewed for a single resource
pool using a search string and are also available as a JSON object
from the same http endpoint.
Testing:
- Added a test that checks if the admission debug page loads correctly
and checks if the reset informational stats http end point works
as expected.
- Did manual stress testing by running the e2e tests and constantly
fetching the admission debug page.
