smengcl opened a new pull request #3051:
URL: https://github.com/apache/ozone/pull/3051
## What changes were proposed in this pull request?
Note we are already using `VOLUME_LOCK` for all write requests. It has been
done in a previous jira.
Just need to acquire the read lock in the appropriate read tenant db table
requests.
(Basically just look for all access to these tables and work backwards:)
```java
// OMMetadataManager
Table<String, OmDBAccessIdInfo> getTenantAccessIdTable();
Table<String, OmDBKerberosPrincipalInfo> getPrincipalToAccessIdsTable();
Table<String, OmDBTenantInfo> getTenantStateTable();
Table<String, String> getTenantGroupTable();
Table<String, String> getTenantRoleTable();
Table<String, String> getTenantPolicyTable();
```
## What is the link to the Apache JIRA
https://issues.apache.org/jira/browse/HDDS-6063
## How was this patch tested?
- All existing tests should pass (after
[HDDS-6239](https://issues.apache.org/jira/browse/HDDS-6239)).
