> Security Wizard: show which principals and keytabs need to be created on

> ------------------------------------------------------------------------------------
>
> Key: AMBARI-2491
> URL: https://issues.apache.org/jira/browse/AMBARI-2491
> Project: Ambari
> Issue Type: Improvement
> Components: ambari-web
> Affects Versions: 1.2.5
> Reporter: Andrii Tkach
> Assignee: Andrii Tkach
> Priority: Critical
> Labels: pull-request-available
> Fix For: 1.2.5
>
> Attachments: AMBARI-2491.patch,
> host-component-principal-keytab-display.png
>
>
> 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.
> 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.
