Description

Accessing logs for an task attempt in the workflow tool in Hue shows "Logs not available for attempt_1433822010707_0001_m_000000_0. Aggregation may not be complete, Check back later or try the nodemanager at quickstart.cloudera:8041"

If the user follows that link, he/she will get "It looks like you are making an HTTP request to a Hadoop IPC port. This is not the correct port for the web interface on this daemon."

We should update the message to use the correct HTTP port. We could also make it more convenient by providing the application's specific page at NM as well instead of just NM's main page.
