Strict Access to Encrypted Zone in Transparent Data Encryption

[#1]

I had setup Transparent data encryption some time back for HDP2.2 by referring steps mentioned at http://hortonworks.com/kb/hdfs-transparent-data-encryption/

I tested my setup, everything worked perfectly except one thing, superuser was able to access the contents from encrypted zone transparently which I think should not work that way, so to restrict your encrypted zone you need to modify below property in /usr/kms-demo/hadoop/etc/hadoop/kms-acls.xml

<property>
<name>hadoop.kms.acl.DECRYPT_EEK</name>
<value>user1,user2</value>
<description> ACL for decryptEncryptedKey CryptoExtension operations.
</description>
</property>

Add list of users for whom you want to give access to your encrypted zone.

Hope this is useful 🙂
