IMPALA-2143: Avoid sending auth credentials over insecure connections

This patch changes the behaviour of the Impala shell to refuse to
attempt an LDAP-authenticated connection to Impala unless SSL/TLS is

A new flag --auth_creds_in_clear_ok is added to suppress this
behaviour. This is similar to Impala's --ldap_passwords_in_clear_ok
flag. The shell will also now print a warning if an insecure
configuration is used.

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.
