> In our production environment, we found that the value of the metric "active_calls_alter_partition" was negative. This is very confusing.
> After checking the HMSHandler.class, we found that the method alter_partitions_with_environment_context called()
> *startTableFunction("alter_partitions", catName, db_name, tbl_name);* 
> *...* 
> *endFunction("alter_partition", oldParts != null, ex, tbl_name);*
> So the metric "active_calls_alter_partition" will be decremented by one after the "alter_partitions" function execution ends, causing the value become a negative number
