The webserver address was always configured as 0.0.0.0 (meaning that the webserver could be reached on any IP for that machine) unless otherwise specified. This is not a correct value to dispay to the user. This patch returns the hostname of the node, when requested, if the webserver host address is 0.0.0.0. This patch also does not print the coordinator link for very simple queries, as it's not necessary and is unnecessarily verbose. This patch also does away with pinging the impalad an extra time per query for finding the host time and webserver address. It instead remembers the webserver address at connect time and displays client local time for every query instead.

Welcome to Impala
Lightning-fast, distributed SQL queries for petabytes of data stored in Apache Hadoop clusters.
Impala is a modern, massively-distributed, massively-parallel, C++ query engine that lets you analyze, transform and combine data from a variety of data sources:
- Best of breed performance and scalability.
- Support for data stored in HDFS, Apache HBase and Amazon S3.
- Wide analytic SQL support, including window functions and subqueries.
- On-the-fly code generation using LLVM to generate CPU-efficient code tailored specifically to each individual query.
- Support for the most commonly-used Hadoop file formats, including the Apache Parquet (incubating) project.
- Apache-licensed, 100% open source.
