------------------------------------

             Summary: Security Wizard: show which principals and keytabs need to be created
on which hosts
                 Key: AMBARI-2491
                 URL: https://issues.apache.org/jira/browse/AMBARI-2491
             Project: Ambari
          Issue Type: Bug
          Components: client
    Affects Versions: 1.2.5
            Reporter: Andrii Tkach
            Assignee: Andrii Tkach
            Priority: Critical
             Fix For: 1.2.5


Currently it is very difficult to know what principals and keytabs need to be created on which
hosts.
We should present this information to the end user in a format that is easy to consume.
The user running the wizard may not be the one who will be creating keytabs and principals.
We can expose the capability to download a csv file and send it to the appropriate person
who may parse the data to create a script to generate principals/keytabs (or do so manually).
Display the attached as a popup after Configure Services step is done.
Let's show it as a popup so that we don't affect any existing navigation/flow.
For generating the content:
Keytab paths are based on the user input
Principal names are based on the user input
NameNode host: show the nn and HTTP principals and keytab paths
JobTracker host: show the jt principal and keytab path
Oozie Server host: show the oozie and HTTP principals and keytab paths
Nagios Server host: show the nagios principal and keytab path
HBase Master host: show the hbase principal and keytab path
Hive Server host: show the hive principal and keytab path
WebHCat Server host: show the HTTP principal and keytab path
ZooKeeper Server host: show the zookeeper principal and keytab path
DataNode host: show the dn principal and keytab path
TaskTracker host: show the tt principal and keytab path
RegionServer host: show the hbase principal and keytab path
If there are duplicated principals on the same host, display it only once.
There are other rules, but please start with this.
Clickng on "Download CSV" downloads the CSV file ("host-principal-keytab-list.csv"). The same
content, except each row is a comma-delimited list with a \n at the end.
