What are the encryption options available in Hadoop?
Hadoop offers several encryption options, including Transparent Data Encryption (TDE), file system encryption, and data-at-rest encryption.
Can you explain how Transparent Data Encryption works?
Transparent Data Encryption encrypts data stored in Hadoop's HDFS, ensuring that data is automatically encrypted and decrypted without requiring changes to applications.
Are there any performance impacts when using encryption?
Yes, there can be performance impacts due to the overhead of encryption and decryption processes, but they are often manageable with proper configuration.
What about encryption for data in transit?
For data in transit, Hadoop supports SSL/TLS to secure data as it moves between nodes, ensuring confidentiality and integrity.
