--------------------------------------
> incorrect metric for active calls —— alter_partitions and alter_partition
> ---------------------------------------------------------------------------

> Key: HIVE-26065
> URL: https://issues.apache.org/jira/browse/HIVE-26065
> Project: Hive
> Issue Type: Bug
> Components: Metastore
> Reporter: DongWei
> Assignee: DongWei
> Priority: Major
>
> 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
