ChenSammi opened a new pull request, #3734: URL: https://github.com/apache/ozone/pull/3734
https://issues.apache.org/jira/browse/HDDS-7197 It uses rocksdb directory name as the jmx bean name. For Schema V2, every rocksdb directory like this, 999998-dn-container.db 999999-dn-container.db While in Schema V3, all rocksdb has the same directory name "container.db". Collision happens when rocksdb per disk volume come to register its metrics to jmx with failure "already exists!" metrics exception. This patch add the disk storage UUID as prefix of bean name. So now the bean name for each Schema V3 rocksdb instance will be storageUUID-container.db, here is an example, DS-d26aea2d-cc3b-42e4-b574-b4644227fa8-ccontainer.db -- This is an automated message from the Apache Git Service.
