IMPALA-10518: Add ImpalaServer interface to retrieve executor membership.
This patch adds an interface to ImpalaServer to retrieve the
current executor membership snapshot from impalad. This involves
sending a thrift request to impalad and receiving a thrift
response. Refactored some code in exec-env into a separate
function in the impala namespace which makes it easier
to populate the needed information for an external frontend.
Testing:
- Ran selected tests for sanity check (no impact is expected
since this is adding a new interface):
- Frontend tests (PlannerTest, CardinalityTest)
- Backend tests under custom_cluster/test_executor_groups.py
- Manually tested with external frontend to ensure it gets
the executor membership snapshot
