[SPARK-15708] Tasks table in Detailed Stage page shows ip instead of hostname under Executor ID/Host

Description

If you go to the detailed Stages page in Spark 2.0, the Tasks table under the Executor ID/Host columns hosts the hostname as an ip address rather then a fully qualified hostname.

The table above it (Aggregated Metrics by Executor) shows the "Address" as the full hostname.

I'm running spark on yarn on latest branch-2.
