> 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
