---------------------------------
Summary: Refactor OzoneManagerLock
Key: HDDS-15909
URL: https://issues.apache.org/jira/browse/HDDS-15909
Project: Apache Ozone
Issue Type: Improvement
Components: OM
Reporter: Tsz-wo Sze
Assignee: Tsz-wo Sze
{code:java}
//OzoneManagerLock
private final Map<Class<? extends Resource>,
Pair<Map<Resource, Striped<ReadWriteLock>>, ResourceLockTracker>>
resourcelockMap;
{code}
The resourcelockMap above is
- inefficient: use a Map (the outer map) for only two elements.
- hard to read/understand: too many layers
- Apache Commons Pair (see HDDS-15908).
- Not type safe: ResourceLockTracker is generic
