test_query_retries.TestQueryRetries is flaky on erasure coding configurations

    Details

      Description

      Multiple tests from test_query_retries.TestQueryRetries hit errors like this (test_retry_query_cancel):

      custom_cluster/test_query_retries.py:321: in test_retry_query_cancel
          self.__validate_runtime_profiles_from_service(impalad_service, handle)
      custom_cluster/test_query_retries.py:435: in __validate_runtime_profiles_from_service
          self.__validate_runtime_profiles(retried_profile, handle.get_handle().id)
      custom_cluster/test_query_retries.py:503: in __validate_runtime_profiles
          retried_query_id = self.__get_query_id_from_profile(retried_runtime_profile)
      custom_cluster/test_query_retries.py:474: in __get_query_id_from_profile
          assert query_id_search, "Invalid query profile, has no query id"
      E   AssertionError: Invalid query profile, has no query id
      E   assert None

      Or this (test_kill_impalad_expect_retries, test_kill_impalad_expect_retry, test_retry_query_hs2):

      custom_cluster/test_query_retries.py:424: in test_retry_query_hs2
          self.hs2_client.get_query_id(handle))
      custom_cluster/test_query_retries.py:508: in __validate_runtime_profiles
          original_query_id)
      custom_cluster/test_query_retries.py:489: in __validate_original_id_in_profile
          assert original_id_search, \
      E   AssertionError: Could not find original id pattern 'Original Query Id: (.*)' in profile:
      ...

      I have only seen these errors on erasure coding so far, and it isn't deterministic.
