----------------------------------
Summary: build should set flag or detect conditions to avoid duplicating
work (was: 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
> real 0m26.564s
> user 0m31.307s
> sys 0m2.346s
> 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.
