[SPARK-3676][SQL] Fix hive test suite failure due to diffs in JDK 1.6…

…/1.7

This is a bug in JDK6: http://bugs.java.com/bugdatabase/view_bug.do?bug_id=4428022

this is because jdk get different result to operate ```double```,
```System.out.println(1/500d)``` in different jdk get different result
jdk 1.6.0(_31) ---- 0.0020
jdk 1.7.0(_05) ---- 0.002
this leads to HiveQuerySuite failed when generate golden answer in jdk 1.7 and run tests in jdk 1.6, result did not match

Closes apache#2517 from scwf/HiveQuerySuite and squashes the following commits:

0cb5e8d [w00228970] delete golden answer of division-0 and timestamp cast #1
