Hadoop - Security

Given the following commands executed in order:

hdfs key create mykey
hdfs dfsadmin -createEncryptionZone -keyName mykey -path /secure

What will happen if you try to write a file to /secure?

AThe file will be stored encrypted automatically

BThe file will be stored unencrypted

CAn error will occur because the key does not exist

DThe file will be compressed but not encrypted

Step-by-Step Solution

Solution:

Step 1: Understand key creation and encryption zone setup
The key 'mykey' is created first, then an encryption zone is created at '/secure' using that key.
Step 2: Analyze file write behavior in encryption zones
Files written inside an encryption zone are automatically encrypted using the zone's key.
Final Answer:
The file will be stored encrypted automatically -> Option A
Quick Check:
Encryption zone + key = automatic encryption [OK]

Quick Trick: Files in encryption zones encrypt automatically [OK]
