IMPALA-9636: Don't run retried query on the blacklisted nodes When a node is blacklisted, it is only placed on the blacklist for a certain period of time. For the current implementation, it is possible that the retried query could end up running on the node that it blacklisted during its original attempt. To avoid same failure for the retried query, we should not schedule query fragment instances on the blacklisted nodes which caused the original query to fail. This patch filters out the executors from executor group for those nodes which are blacklisted during its original attempt when make schedule for the retried query. Adds new test cases test_retry_exec_rpc_failure_before_admin_delay() and test_retry_query_failure_all_executors_blacklisted() for retried queries which are triggered by RPC failure and blacklist timeout are triggered by adding delay before admission. Testing: - Passed test_query_retries.py, including the new test cases. - Passed core tests.
