Open hadoop webui remediation

Using Console

Using CLI

To remediate the misconfiguration “Hadoop HDFS Port Should Not Be Open” for GCP using GCP CLI, follow these steps:

Open the Cloud Shell from the GCP console.
Run the following command to list all the instances in your project:
```
gcloud compute instances list
```
Identify the instance that has the Hadoop HDFS port open.
Run the following command to SSH into the instance:
```
gcloud compute ssh [INSTANCE_NAME]
```
Replace [INSTANCE_NAME] with the name of the instance.
Once you are logged in to the instance, run the following command to stop the Hadoop HDFS service:
```
sudo systemctl stop hadoop-hdfs-datanode
```
Run the following command to disable the Hadoop HDFS service:
```
sudo systemctl disable hadoop-hdfs-datanode
```
Edit the Hadoop HDFS configuration file to remove the port configuration. The configuration file is usually located at /etc/hadoop/conf/hdfs-site.xml.
Save the changes and exit the editor.
Run the following command to start the Hadoop HDFS service:
```
sudo systemctl start hadoop-hdfs-datanode
```
Finally, run the following command to enable the Hadoop HDFS service to start automatically on boot:
```
sudo systemctl enable hadoop-hdfs-datanode
```
Exit the SSH session by running the following command:
```
exit
```

With these steps, you have successfully remediated the misconfiguration “Hadoop HDFS Port Should Not Be Open” for GCP using GCP CLI.
