------------------------------------------
Summary: 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
Reporter: Zoltán Borók-Nagy
Assignee: Zoltán Borók-Nagy
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.
