You may query the cluster probe endpoint to check if the node which received the request can be taken down for maintenance, if the server replies back '412 Precondition Failed' this means you will lose HA. '200 OK' means you are okay to proceed.

```
curl http://minio1:9001/minio/health/cluster?maintenance=true
HTTP/1.1 412 Precondition Failed
Accept-Ranges: bytes
Content-Length: 0
Server: MinIO
Vary: Origin
X-Amz-Bucket-Region: us-east-1

    @Test
    void testDoFilter_alreadyAuthenticated_shouldProceed() throws Exception {
        // Initialize filter first
        initializeFilter();

        // Test request with existing authentication should proceed
        Properties props = new Properties();
        props.setProperty("jcifs.smb.client.domain", "TEST_DOMAIN");
        CIFSContext context = new BaseContext(new PropertyConfiguration(props));

```

Distributed instances are now accessible on the host using the Minio CLI on port 9000 and the Minio Web Console on port 9001. Proceed to access the Web browser at <http://127.0.0.1:9001/>. Here 4 MinIO server instances are reverse proxied through Nginx load balancing.

Now let us proceed to run our select example to query for `Location` which matches `United States`.

```sh
$ python3 select.py

            try {
