> IMPALA-6663 adds a web page for catalogd to show all in-progress operations.
> While doing a stree test for IMPALA-10563, I found that the summary tab
> doesn't sum up the operations as I expected.
> !catalogd_operations.png|width=869,height=627!
> As shown by the snapshot, I have 5 in-progress FINALIZE_INSERT_INTO
> operations. But in the "In-progress Catalog Operations Summary" tab, it shows
> 1. It makes sense to me to show 5 as well.
> I think the reason is in be/src/catalog/catalog-server.cc, we only sum up
> requests by tables:
> {code:c++}
> void CatalogServer::OperationUsageUrlCallback(
> const Webserver::WebRequest& req, Document* document) {
> ...
> // Create a summary and add it to the document
> map<string, int> aggregated_operations;
> for (const auto& catalog_op : opeartion_usage.catalog_op_counters) {
> ++aggregated_operations[catalog_op.catalog_op_name]; // <---- should add
> catalog_op.op_counter here
> }
> ...
> }
> {code}
