Tsuyoshi OZAWA commented on YARN-1789:
--------------------------------------
[~ajisakaa] and [~jlowe], I checked code around *Summary. IIUC,
ApplicationSummary doesn't exist on YARN side, because it's a application-side
class. On the other hand, LogAggregationService logs applications information,
but it uses ApplicationId(not app name). It doesn't break one-app-per-line
output manner, so we don't have points to fix. Please correct me if I get
wrong. Thanks.

> ApplicationSummary is not escaping newlines in the app name. This can result
> in an application summary log entry that spans multiple lines when users are
> expecting one-app-per-line output.
