# Cause
When disabling Kerberos, the stack advisor recommendations are not properly
applied due to the order of operations and various conditionals.
# Solution
Ensure that the stack advisor recommendations are properly applied when
disabling Kerberos.

Testing
-------
Manually tested - enabled Kerberos, disabled Kerberos, enabled Kerberos again.
Compared configurations to ensure configuration changes were set properly -
espically the HBASE coprocessor properties.
# Local test results:
Java test passed, unlrealted python test failed
# Jenkins test results: PENDING
Thanks,
Robert Levas
