*Reason*
That is because {{AppStatusStore.applicationInfo()}} accesses an empty view
(iterator) returned by {{InMemoryStore}}.
AppStatusStore
{code:java}
def applicationInfo(): v1.ApplicationInfo = {
store.view(classOf[ApplicationInfoWrapper]).max(1).iterator().next().info
}
{code}
InMemoryStore
{code:java}
public KVStoreView view(Class type){
InstanceList list = inMemoryLists.get(type);
return list != null ? list.view() : emptyView();
}
{code}
During the initialization of {{SparkContext}}, it first starts the Web UI
(SparkContext: L475 _ui.foreach(_.bind())) and then setup the
{{LiveListenerBus}} thread (SparkContext: L608 {{setupAndStartListenerBus()}})
for dispatching the {{SparkListenerApplicationStart}} event (which will trigger
writing the requested {{ApplicationInfo}} to {{InMemoryStore}}).
