Zoltan Chovan created HIVE-23391: ------------------------------------ Summary: Change requested lock for ALTER TABLE ADD COLUMN to DDL_SHARED Key: HIVE-23391 URL: https://issues.apache.org/jira/browse/HIVE-23391 Project: Hive Issue Type: Improvement Reporter: Zoltan Chovan
A long running query can block a simple add column query, as the add column will require a DDL_EXCLUSIVE lock currently. By changing this to a shared lock, this metadata only query can be executed without having to wait for the previous query to finish. -- This message was sent by Atlassian Jira (v8.3.4#803005)
