Subject [jira] [Created] (AMBARI-2415) Warn/prompt user to adjust Service props when they change user/groups in Misc
Date Tue, 18 Jun 2013 12:35:19 GMT
Andrii Tkach created AMBARI-2415:

             Summary: Warn/prompt user to adjust Service props when they change user/groups
in Misc
                 Key: AMBARI-2415
             Project: Ambari
          Issue Type: Improvement
          Components: client
    Affects Versions: 1.2.4
            Reporter: Andrii Tkach
            Assignee: Andrii Tkach
             Fix For: 1.2.5

During install, you can modify the user accounts + group the services run under (such as hdfs,
mapred, etc).
If the customer customizes these settings, in some cases, they also need to modify some service
props (like for mapred or oozie, etc). Unless the user is aware of this, they will likely
forget to do this. Then when they finish cluster install and try to run jobs against the cluster,
things fail.
We should protect + inform the customer when they modify users + group under the Misc tab.
1) When user changes a user or group under the Customize Services > Misc tab, popup a dialong
2) Warning: you must also change these Service properties.
3) List a four-column table, with the Service, the Property, and the Current Value, and the
Adjusted Value
4) User can click: Apply, Ignore, Undo
Apply makes the prop changes
Ignore just leaves the props as they are but leaves user + group settings as they are
Undo leaves props, and reverts user + groups text fields
