[jira] [Created] (IMPALA-9706) Test that queries are not retried if they cause an impalad to crash

Sahil Takiar created IMPALA-9706:
------------------------------------

             Summary: Test that queries are not retried if they cause an impalad to crash
                 Key: IMPALA-9706
                 URL: https://issues.apache.org/jira/browse/IMPALA-9706
             Project: IMPALA
          Issue Type: Sub-task
          Components: Backend
            Reporter: Sahil Takiar


IMPALA-9199 adds the core functionality for retrying queries, but it does not contain any tests that validate a query is not retried if the query itself caused an impalad to crash. If a query causes an impalad to crash, it should not be retried because it will likely just cause the impalad to crash again.

There may not be a straightforward way to do this. I'm not sure how Impala can differentiate between query "x" causing a crash vs. anything else that can cause an impalad to crash. However, opening this JIRA to (1) document that this could be an issue, and (2) brainstorm any ideas.
