> Project: IMPALA
> Issue Type: Improvement
> Components: Clients

> After IMPALA-12048 is resolved, we can see the query progress of a query on
> the /queries page. Unlike scan progress, it uses the completion count of
> query fragment instances to calculate progress, providing a more accurate
> reflection of query execution progress, especially for computation-intensive
> queries (such as TPC-DS query 78). Perhaps we should also use query progress
> instead of scan progress in the dynamic progress reporting for the impala
> shell, to provide more accurate query completion progress reports and avoid
> cases where the scan is complete but the query still needs a long time to
> finish computation even though the progress is reported as 100%.
