> 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}
>  cc [~tmate]
