> When I enable AHS via yarn.ahs.enabled, the app history is still not visible in AHS webUI. This is due to NullApplicationHistoryStore as yarn.resourcemanager.history-writer.class. It would be good to have just one key to enable basic functionality.
> yarn.ahs.fs-history-store.uri uses {code}${hadoop.log.dir}{code}, which is local file system location. However, FileSystemApplicationHistoryStore uses DFS by default.
