**Example 1: To update an HTTP namespace**

The following ``update-http-namespace`` example updates the specified HTTP namespace's description. ::

    aws servicediscovery update-http-namespace \
        --id ns-abcd1234xmpl5678 \
        --updater-request-id abcd1234-5678-90ab-cdef-xmpl12345678 \
        --namespace Description="The updated namespace description."

Output::

    {
        "OperationId": "abcd1234-5678-90ab-cdef-xmpl12345678"
    }

To confirm that the operation succeeded, you can run ``get-operation``. For more information, see `get-operation <https://docs.aws.amazon.com/cli/latest/reference/servicediscovery/get-operation.html>`__ .

**Example 2: To update an HTTP namespace using ARN**

The following ``update-http-namespace`` example updates the specified HTTP namespace using its ARN. ::

    aws servicediscovery update-http-namespace \
        --id arn:aws:servicediscovery:us-west-2:123456789012:namespace/ns-abcd1234xmpl5678 \
        --updater-request-id abcd1234-5678-90ab-cdef-xmpl12345678 \
        --namespace Description="The updated namespace description."

Output::

    {
        "OperationId": "abcd1234-5678-90ab-cdef-xmpl12345678"
    }
