Daniel Vimont updated HBASE-14879:
----------------------------------
    Attachment: archetype_mr_prototype.zip

Attaching a zip file, {{archetype_mr_prototype.zip}}, containing the compon=
ents of a Maven archetype suitable for testing in a sandbox environment. It=
 is provided separately here so that folks can try it out and comment on it=
 before we try to incorporate it into the HBase project and push the archet=
ype into the Maven central repository.

The MapReduce job code that is generated from this archetype is called {{Co=
pyTableExample.java}}, and it is derived from {{CopyTable}} in the HBase pr=
oject. Also included is a corresponding test class {{TestCopyTableExample.j=
ava}}.

This archetype generates a prefab project for the user which (a) automatica=
lly establishes for them all required Maven dependencies, (b) provides a co=
mplete example of HBase-oriented MapReduce job code, and (c) provides a com=
plete example of test code showing how to use the HBaseTestUtility to easil=
y and effectively test a MapReduce job.

It's recommended to do the following in a separate sandbox environment, not=
 in an active development environment. (I use VirtualBox to set up a fresh =
Ubuntu environment whenever I need a new sandbox.)

INSTRUCTIONS
(1) Download and unzip {{archetype_mr_prototype.zip}}.
(2) Go into the {{archetype_mr_prototype}} directory, and execute: {{mvn in=
stall}}
This will install the archetype (which is called {{hbase-mapreduce-job-arch=
etype}}, version {{1.1.2-alpha}}) into your local Maven repository.
(3) To create a new project based upon the archetype, go to the directory i=
n which you want the project folder and its contents to be created, and exe=
cute the following:
  {{mvn archetype:generate -DarchetypeCatalog=3Dlocal}}
This will interactively ask you to (a) choose the number of the archetype y=
ou want to use from a numbered list that is displayed (in this case, choose=
 the number corresponding to =E2=80=9Chbase-mapreduce-job-archetype=E2=80=
=9D), (b) specify groupId (e.g., =E2=80=9Corg.example=E2=80=9D), (c) specif=
y artifactId (e.g., =E2=80=9Ctest-hbase-mapreduce-project=E2=80=9D), (d) sp=
ecify version (default is =E2=80=9C1.0-SNAPSHOT=E2=80=9D), and (e) specify =
package (e.g., =E2=80=9Corg.example.testpackage=E2=80=9D).

Your generated project components will be found in a new directory named wi=
th the artifactId value that you specified above. Going to the new project =
directory and running {{mvn install}} from the command line should result i=
n downloading of all dependencies, compiling of the provided Java classes, =
and running (hopefully to success) of all the tests in the test class. Note=
 that the tests could take 3 to 5 minutes to complete.
