[SPARK-2678][Core][SQL] A workaround for SPARK-2678

JIRA issues: - Main: [SPARK-2678](https://issues.apache.org/jira/browse/SPARK-2678) - Related: [SPARK-2874](https://issues.apache.org/jira/browse/SPARK-2874) Related PR: - apache#1715 This PR is both a fix for SPARK-2874 and a workaround for SPARK-2678. Fixing SPARK-2678 completely requires some API level changes that need further discussion, and we decided not to include it in Spark 1.1 release. As currently SPARK-2678 only affects Spark SQL scripts, this workaround is enough for Spark 1.1. Command line option handling logic in bash scripts looks somewhat dirty and duplicated, but it helps to provide a cleaner user interface as well as retain full downward compatibility for now. Author: Cheng Lian <lian.cs.zju@gmail.com> Closes apache#1801 from liancheng/spark-2874 and squashes the following commits: 8045d7a [Cheng Lian] Make sure test suites pass 8493a9e [Cheng Lian] Using eval to retain quoted arguments aed523f [Cheng Lian] Fixed typo in bin/spark-sql f12a0b1 [Cheng Lian] Worked arount SPARK-2678 daee105 [Cheng Lian] Fixed usage messages of all Spark SQL related scripts (cherry picked from commit a6cd311) Signed-off-by: Patrick Wendell <pwendell@gmail.com>
