Encrypt and store them in configuration files or environment variables and decrypt them when needed. // The password is stored in environment variables for identity authentication. Before running this example, set the environment variable HETUENGINE_PASSWORD.
Applications need only to encrypt specified sensitive data. Services are not affected during the encryption process. Based on file system data encryption, Hive provides table-level encryption and HBase provides column family-level encryption.
Encrypt and store them in configuration files or environment variables and decrypt them when needed. // The password is stored in environment variables for identity authentication. Before running this example, set the environment variable HETUENGINE_PASSWORD.
The default value is 3des, indicating that 3DES algorithm is used to encrypt data. The value can also be set to rc4.
This key is used to encrypt and decrypt the newly stored data. The old key is not deleted, and it is used to decrypt data encrypted using the old key.
The value cannot contain special characters such as ;|&><'$ CAUTION: When entering a parameter containing sensitive information (for example, login password), you can add an at sign (@) before the parameter name to encrypt the parameter value.
Data Disk Key Name: Select the name of the key used to encrypt the data disk. By default, the default master key named evs/default is selected. You can select another master key from the drop-down list.
For example, if the Loader client installation directory is /opt/hadoopclient/Loader, run the following command: cd /opt/hadoopclient/Loader/loader-tools-1.99.3 Run the following command to encrypt the non-encrypted password: .

Table 1 IoTDB performance optimization parameters Parameter Description Default Value Optimization Suggestion SSL_ENABLE Whether to encrypt the channel between the client and server using SSL true true indicates that SSL encryption is enabled, and false indicates that SSL encryption
To obtain the port number, click Configurations and search for yarn.resourcemanager.port in the search box. hadoop.rpc.protection: specifies whether to encrypt the RPC stream of each Hadoop module. The default value is privacy.
The value cannot contain special characters such as ;|&><'$ CAUTION: When entering a parameter containing sensitive information (for example, login password), you can add an at sign (@) before the parameter name to encrypt the parameter value.
