Deleting a Namespace

This section describes how to delete a namespace to release storage space.

Services in the namespace have been stopped and are not shared.
If the object service has been enabled for the namespace, the .snapshot and .recyclebininternal directories in the namespace will cause the namespace to fail to be deleted. Ensure that the snapshot directory and recycle bin directory are invisible for the namespace and the namespace does not contain any object.
If the snapshot directory is invisible, you can directly modify it according to steps in Modifying Properties of a Namespace. If the recycle bin directory is invisible, run the following command on the CLI:
```
change hdfs general name=Namespace name is_trash_visible=false
```

Choose Resources > Resources > Namespace.
Select the desired account from the Account drop-down list in the upper left corner.
Select one or more desired namespaces and click Delete.

You can also click More on the right of a desired namespace and select Delete.
Confirm your operation as prompted.

If the object service is enabled, after deleting a namespace, you must wait at least 5 minutes (maximum 10 minutes) before creating another namespace with the same name.
