If using the Hadoop KMS based provider, then /etc/hadoop/kms-acls.xml needs to be updated to include users with appropriate permissions. For more details on how to edit that file please look at Hadoop Key Management Server.
If using the file-based provider, the password to control access to the file needs to be set. To set the password please add the following property to your cdap-security.xml. The file (cdap-security.xml ) needs to be created if not already present.
<property>
<name>security.store.file.password</name>
<value>your password</value>
