> 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
