Matt Foley commented on HADOOP-13382:
-------------------------------------
Response to the Hadoop QA complaint: This patch seeks to produce no functional
change in the behavior of the code, therefore there are no new unit tests
needed. There are no new negative tests needed either, because if the patch
breaks anything, it will be a gross breakage of hadoop-openstack. Since all
existing unit tests continue to work correctly, that's sufficient.

> Key: HADOOP-13382
> URL: https://issues.apache.org/jira/browse/HADOOP-13382
> Project: Hadoop Common
> Issue Type: Improvement
> Components: build
> Affects Versions: 2.8.0
> Reporter: Matt Foley
> Assignee: Matt Foley
> Attachments: HADOOP-13382-branch-2.000.patch,
> HADOOP-13382-branch-2.8.000.patch, HADOOP-13382.000.patch

> In branch-2.8 and later, the patches for various child and related bugs
> listed in HADOOP-10105, most recently including HADOOP-11613, HADOOP-12710,
> HADOOP-12711, HADOOP-12552, and HDFS-10623, eliminate all use of
> "commons-httpclient" from Hadoop and its sub-projects (except for
> hadoop-tools/hadoop-openstack; see HADOOP-11614).
> However, after incorporating these patches, "commons-httpclient" is still
> listed as a dependency in these POM files:
> * hadoop-project/pom.xml
> * hadoop-yarn-project/hadoop-yarn/hadoop-yarn-registry/pom.xml
> We wish to remove these, but since commons-httpclient is still used in many
> files in hadoop-tools/hadoop-openstack, we'll need to _add_ the dependency to
> * hadoop-tools/hadoop-openstack/pom.xml
> (We'll add a note to HADOOP-11614 to undo this when commons-httpclient is
> removed from hadoop-openstack.)
> In 2.8, this was mostly done by HADOOP-12552, but the version info formerly
> inherited from hadoop-project/pom.xml also needs to be added, so that is in
> the branch-2.8 version of the patch.
