>                 Key: YARN-6766
>                 URL: https://issues.apache.org/jira/browse/YARN-6766
>             Project: Hadoop YARN
>          Issue Type: Improvement
>          Components: webapp
>    Affects Versions: 2.8.1, 3.0.0-alpha3
>            Reporter: Daniel Templeton
>            Priority: Minor
>              Labels: newbie

> The various {{*AppsBlock}} classes are riddled with statements like:
> {code}.append(appInfo.getReservedVCores() == -1 ? "N/A" : String.valueOf(appInfo.getReservedVCores())){code}
> The code would be much cleaner if there were a utility method for that operation, e.g.:
> {code}.append(printData(appInfo.getReservedCores())){code}
