    - Sqoop2
      - Sqoop2 Connector Support
        Connector support differs for each version of Sqoop2.
      - Configuring Sqoop2
        Configure Kerberos Authentication for Sqoop2
        You can configure Sqoop2 to use Kerberos authentication. When Sqoop2 uses Kerberos authentication, the cluster and other components that work with Sqoop2, such as Hue, must also use Kerberos authentication.
        Configure MapR-SASL for Sqoop2
        This section describes how to configure Sqoop2 to use MapR-SASL. Starting with the EEP 4.0 release, for secure clusters, MapR-SASL is automatically configured for Sqoop2 and you can skip the steps outlined in this section.
        Configure SSL for Sqoop2
        As of Sqoop 1.99.7, you can configure SSL to enable encrypted communications between the Sqoop2 server and its clients. Starting with the EEP 4.0 release, for secure clusters, SSL is automatically configured for Sqoop2 and you can skip the steps outlined in this section.
        Configure Repository Encryption for Sqoop2
        As of Sqoop 1.99.7, you can configure the Sqoop2 repository to encrypt password data.
      - Using Sqoop2
      - Sqoop 1.99.7 API Changes

Configure Repository Encryption for Sqoop2

As of Sqoop 1.99.7, you can configure the Sqoop2 repository to encrypt password data.

About this task

IMPORTANT This component is deprecated. Hewlett Packard Enterprise recommends using an alternate product. For more information, see Discontinued Ecosystem Components.

Procedure

Stop the Sqoop2 server.

maprcli node services -name sqoop2 -action stop -nodes <space delimited list of nodes>

In the sqoop.properties file (/opt/mapr/sqoop/sqoop-<version>/conf/sqoop.properties), configure the repository encryption related properties. For example:

org.apache.sqoop.security.repo_encryption.enabled=true
org.apache.sqoop.security.repo_encryption.password=<ssl-keystore-password>
org.apache.sqoop.security.repo_encryption.hmac_algorithm=HmacSHA256
org.apache.sqoop.security.repo_encryption.cipher_algorithm=AES
org.apache.sqoop.security.repo_encryption.cipher_key_size=16
org.apache.sqoop.security.repo_encryption.cipher_spec=AES/CBC/PKCS5Padding
org.apache.sqoop.security.repo_encryption.initialization_vector_size=16
org.apache.sqoop.security.repo_encryption.pbkdf2_algorithm=PBKDF2WithHmacSHA1
org.apache.sqoop.security.repo_encryption.pbkdf2_rounds=4000

Remove the Sqoop2 repository.
```
rm -rf /opt/mapr/sqoop/repository
```

Start the Sqoop2 server.

maprcli node services -name sqoop2 -action start -nodes <space delimited list of nodes>
