kevinrr888 opened a new issue, #6045:
URL: https://github.com/apache/accumulo/issues/6045
**Describe the bug**
If debug is enabled, creating a namespace results in this debug log in the
Manager log:
```

```
This is because of the check that ensures the namespace does not exist
before creating it. When this is called, the namespace does not exist (which is
expected), but it logs this error message.
**Versions (OS, Maven, Java, and others, as appropriate):**
- 2.1, maybe 4.0 as well
**To Reproduce**
Create a namespace in 2.1 with NamespaceOperations.create()
**Expected behavior**
creating a namespace should not result in this log
