-----------------------------
Summary: Potential connection pool leak in JDBC pushdown
configuration
Key: KYLIN-6127
URL: https://issues.apache.org/jira/browse/KYLIN-6127
Project: Kylin
Issue Type: Bug
Affects Versions: 5.0.5
Reporter: liyang
Assignee: liyang
Fix For: 5.0.6
Changing project-level JDBC pushdown configuration replaces the project
connection manager without closing the previous connection pool. Repeated
updates can leave orphaned physical connections and exhaust a shared external
database quota.
Fix direction: close the replaced connection manager after atomically
installing the new manager for the project.
