# Prerequisites: Steps you have to complete before you can upload data with DSBulk
<a name="dsbulk-upload-prequs"></a>

You must complete the following tasks before you can start this tutorial.

1. If you have not already done so, sign up for an AWS account by following the steps at [Setting up AWS Identity and Access Management](accessing.md#SettingUp.IAM).

1. Create credentials by following the steps at [Create and configure AWS credentials for Amazon Keyspaces](access.credentials.md).

1. Create a JKS trust store file.

   1.  Download the following digital certificates and save the files locally or in your home directory.

      1. AmazonRootCA1

      1. AmazonRootCA2

      1. AmazonRootCA3

      1. AmazonRootCA4

      1. Starfield Class 2 Root (optional – for backward compatibility)

      To download the certificates, you can use the following commands.

      ```
      curl -O https://www.amazontrust.com/repository/AmazonRootCA1.pem
      curl -O https://www.amazontrust.com/repository/AmazonRootCA2.pem
      curl -O https://www.amazontrust.com/repository/AmazonRootCA3.pem
      curl -O https://www.amazontrust.com/repository/AmazonRootCA4.pem
      curl -O https://certs.secureserver.net/repository/sf-class2-root.crt
      ```
**Note**  
Amazon Keyspaces previously used TLS certificates anchored to the Starfield Class 2 CA. AWS is migrating all AWS Regions to certificates issued under Amazon Trust Services (Amazon Root CAs 1–4). During this transition, configure clients to trust both Amazon Root CAs 1–4 and the Starfield root to ensure compatibility across all Regions.

   1. Convert the digital certificates into trustStore files and add them to the keystore.

      ```
      openssl x509 -outform der -in AmazonRootCA1.pem -out temp_file.der
      keytool -import -alias amazon-root-ca-1 -keystore cassandra_truststore.jks -file temp_file.der
      
      openssl x509 -outform der -in AmazonRootCA2.pem -out temp_file.der
      keytool -import -alias amazon-root-ca-2 -keystore cassandra_truststore.jks -file temp_file.der
      
      openssl x509 -outform der -in AmazonRootCA3.pem -out temp_file.der
      keytool -import -alias amazon-root-ca-3 -keystore cassandra_truststore.jks -file temp_file.der
      
      openssl x509 -outform der -in AmazonRootCA4.pem -out temp_file.der
      keytool -import -alias amazon-root-ca-4 -keystore cassandra_truststore.jks -file temp_file.der
                   
      openssl x509 -outform der -in sf-class2-root.crt -out temp_file.der
      keytool -import -alias cassandra -keystore cassandra_truststore.jks -file temp_file.der
      ```

      In the last step, you need to create a password for the keystore and trust each certificate. The interactive command looks like this.

      ```
      Enter keystore password:  
      Re-enter new password:

1. Set up the Cassandra Query Language shell (cqlsh) connection and confirm that you can connect to Amazon Keyspaces by following the steps at [Using `cqlsh` to connect to Amazon Keyspaces](programmatic.cqlsh.md). 

1. Download and install DSBulk. 
**Note**  
The version shown in this tutorial might not be the latest version available. Before you download DSBulk, check the [DataStax Bulk Loader download page](https://downloads.datastax.com/#bulk-loader) for the latest version, and update the version number in the following commands accordingly.

   1. To download DSBulk, you can use the following code.

      ```
      curl -OL https://downloads.datastax.com/dsbulk/dsbulk-1.8.0.tar.gz
      ```

   1. Then unpack the tar file and add DSBulk to your `PATH` as shown in the following example.

      ```
      tar -zxvf dsbulk-1.8.0.tar.gz
      # add the DSBulk directory to the path
      export PATH=$PATH:./dsbulk-1.8.0/bin
      ```

   1. Create an `application.conf` file to store settings to be used by DSBulk. You can save the following example as `./dsbulk_keyspaces.conf`. Replace `localhost` with the contact point of your local Cassandra cluster if you are not on the local node, for example the DNS name or IP address. Take note of the file name and path, as you're going to need to specify this later in the `dsbulk load` command. 

      ```
      datastax-java-driver {
        basic.contact-points = [ "localhost"]
        advanced.auth-provider {
              class = software.aws.mcs.auth.SigV4AuthProvider
              aws-region = us-east-1
        }
      }
      ```

   1. To enable SigV4 support, download the shaded `jar` file from [GitHub](https://github.com/aws/aws-sigv4-auth-cassandra-java-driver-plugin/releases/) and place it in the DSBulk `lib` folder as shown in the following example.

      ```
      curl -O -L https://github.com/aws/aws-sigv4-auth-cassandra-java-driver-plugin/releases/download/4.0.6-shaded-v2/aws-sigv4-auth-cassandra-java-driver-plugin-4.0.6-shaded.jar
      ```
