Review request for Ambari, Jonathan Hurley, Larry McCay, Robert Nettleton, and
Sid Wagle.
Bugs: AMBARI-12772
https://issues.apache.org/jira/browse/AMBARI-12772
Repository: ambari
Description
-------
#STR
Install cluster via blueprints
Enable Kerberos security
Add host via blueprints
#Result
Adding hosts freeze forever
In ambari-server.log:
```
The KDC administrator credentials must be set in session by updating the
relevant Cluster resource.This may be done by issuing a PUT to the
api/v1/clusters/(cluster name) API entry point with the following payload:
{
"session_attributes" : {
"kerberos_admin" : {"principal" : "(PRINCIPAL)", "password" : "(PASSWORD)"}
}
```
#Cause
This is caused because the KDC administrative credentials are not available
when needed during the add host process. If set in the HTTP session, the
credentials are not accessible since the Kerberos logic is executed outside the
scope of that HTTP session.
#Solution
Store the KDC credentials to a _more secure_ global credential store that is
accessible no matter what the context is. This storage facility is in-memory
and has a retention period of 90 minutes. This solution refactors the current
CredentialStoreService and MasterKeyService classes to allow for file-based and
in-memory implementations. It also paves the way for future changes to allow
for the KDC administrative credentials to be persisted indefinitely.
*Note:* This patch is rather large due to refactoring the
CredentialStoreService and releated classes in an effort to make way for future
features related to storing sensitive data.

Testing
-------
Manually tested the following on trunk and branch-2.1:
- backwards compatibailiy with storing and retrieving the master key and key
store data
- adding a host on a non-kerberized cluster
- adding a host on a kerberized cluster
- credential retention timeout
