[jira] [Commented] (IMPALA-9569) Query progress bar freezes when a

Commit 1fbca6d43bc3fb08b9e04a4eb8e1c1dcf7c67712 in impala's branch refs/heads/master from stiga-huang

IMPALA-9569: Fix progress bar and live_summary to show info of the retried query
Impala-shell periodically calls GetExecSummary() when the query is
queuing or running. If the query is being retried, GetExecSummary()
should return the TExecSummary of the retried query. So the progress bar
and live_summary can reflect the most recent state.
This patch also modifies get_summary() to return retry information in
error_logs of TExecSummary. Impala-shell and other clients can print the
info right after the query starts being retried. Modified impala-shell
to print the retried query link when the retried query is running.
Example output when the retried query is running:
Query: select count(*) from functional.alltypes where bool_col = sleep(60)
Query submitted at: 2020-06-18 22:08:49 (Coordinator: http://quanlong-OptiPlex-BJ:25000)
Query progress can be monitored at: http://quanlong-OptiPlex-BJ:25000/query_plan?query_id=9444fe7f0df0da28:29134b0800000000
Failed due to unreachable impalad(s): quanlong-OptiPlex-BJ:22001
Retrying query using query id: 5748d9a3ccc28ba8:a75e2fab00000000
Retried query link: http://quanlong-OptiPlex-BJ:25000/query_plan?query_id=5748d9a3ccc28ba8:a75e2fab00000000

Tests:
- Manually verify the progress bar and live_summary work when the query
is being retried.
- Add tests in test_query_retries.py to validate the get_summary()
results.

> Recently noticed this since the query progress bar is now enabled by default. When a query is retried the progress bar just freezes at its current position and doesn't make any more progress.
