[jira] [Updated] (HIVE-26065) incorrect metric for active calls —— alter_partitions and alter_partition
[ https://issues.apache.org/jira/browse/HIVE-26065?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
DongWei updated HIVE-26065:
---------------------------
Description:
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
