IMPALA-9213: Add query retry info to GetLog result
Beeswax clients use get_log() to retrieve the warning/error message
after the query finishes. HS2 clients use GetLog() for the same purpose.
This patch adds the retry information into the returned result if the
query is retried. So clients that print the log can show the original
query failure and the retried query id.
This patch also modifies impala-shell to extract the retried query id
and print the retried query link.
Here's an example of the impala-shell output:
Query: select count(*) from functional.alltypes where bool_col = sleep(60)
Query submitted at: 2020-06-18 21:23:52 (Coordinator:
http://quanlong-OptiPlex-BJ:25000)
Query progress can be monitored at:
http://quanlong-OptiPlex-BJ:25000/query_plan?query_id=7944ffee4d81cdd4:e7f9357a00000000
+----------+
| count(*) |
+----------+
| 3650 |

WARNINGS: Original query failed:
Failed due to unreachable impalad(s): quanlong-OptiPlex-BJ:22001
Query has been retried using query id: 934b2734f67a1161:a0dbd60200000000
Retried query link:
http://quanlong-OptiPlex-BJ:25000/query_plan?query_id=934b2734f67a1161:a0dbd60200000000
Tests:
- Add tests in test_query_retries.py to verify client logs returned
from GetLog().
- Run test_query_retries.py.
- Manually run queries in impala-shell and kill impalads. Verify
printed messages when the retried queries succeed or fail.
