[jira] [Work logged] (HIVE-26065) incorrect metric for active calls —— alter_partitions and alter_partition
[ https://issues.apache.org/jira/browse/HIVE-26065?focusedWorklogId=746784&page=com.atlassian.jira.plugin.system.issuetabpanels:worklog-tabpanel#worklog-746784 ]

Work Description: Tuan8888 opened a new pull request #3133:
URL: https://github.com/apache/hive/pull/3133
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
