build should set flag or detect conditions to avoid deplicating work
--------------------------------------------------------------------

                 Key: HIVE-1177
                 URL: https://issues.apache.org/jira/browse/HIVE-1177
             Project: Hadoop Hive
          Issue Type: Improvement
          Components: Build Infrastructure
            Reporter: Edward Capriolo
            Priority: Minor


I made an ant target quick-test, which differs from test in that it
has no dependencies.
 <target name="quick-test">
   <iterate target="test"/>
 </target>

<target name="test" depends="clean-test,jar">
 <iterate target="test"/>
 <iterate-cpp target="test"/>
</target>

time ant -Dhadoop.version='0.18.3' -Doffline=true
-Dtestcase=TestCliDriver -Dqfile=alter1.q quick-test
BUILD SUCCESSFUL
Total time: 15 seconds

real    0m16.250s
user    0m20.965s
sys     0m1.579s

time ant -Dhadoop.version='0.18.3' -Doffline=true
-Dtestcase=TestCliDriver -Dqfile=alter1.q test
BUILD SUCCESSFUL
Total time: 26 seconds

Some makefiles set flags files like "make.ok", that allow the build process to intelligently
skip steps that are already done. Currently, a target like test has no way of determining
state and will re-issue dependent targets like clean-test,jar (and there dependents). 

Suggestion:
Hive should set flags or intelligently determine the state of the build and save cpu development
time. Targets should not re-execute unless a clean is explicitly given.
