Component/s: Backend
> Workload management throws TableNotFoundException: Table not found:
> sys.impala_query_log on first execution

> Key: IMPALA-14468
> URL: https://issues.apache.org/jira/browse/IMPALA-14468
> Project: IMPALA
> Issue Type: Bug
> Components: Backend
> Reporter: Zoltán Borók-Nagy
> Assignee: Zoltán Borók-Nagy
> Priority: Major
> Labels: workload-management
>
> When Workload management is used first, CatalogD reports error Table not
> found: sys.impala_query_log. (also for sys.impala_query_live)
> It is because during InitWorkloadManagement() we issue a ResetMetadata()
> request against sys.impala_query_log to retrieve its schema version. If the
> request fails with TableNotFound, we create the table. In other words, the
> current initialization of workload management generates error messages even
> when everything is going fine, and this can confuse users.
> Instead of calling ResetMetadata() we can test the existence of the workload
> management tables (sys.impala_query_log and sys.impala_query_live) first.
