+# HAWQ Ambari Plugin
+
+hawq-ambari-plugin helps users install HAWQ and PXF using Ambari.
+
+To ensure that Ambari recognizes HAWQ and PXF as services that can be 
installed for a specific stack, the following manual steps are required:
+ * Add HAWQ and PXF metainfo.xml files (containing metadata about the 
service) under the stack to be installed.
+ * Add repositories where HAWQ and PXF rpms reside, so that Ambari can use 
it during installation. This requires updating repoinfo.xml under the stack 
HAWQ and PXF is to be added.
+ * If a stack is already installed using Ambari, add repositories to the 
existing stack using the Ambari REST API.
+
+
+## Source Code
+Source code directory structure of the hawq-ambari-plugin is as follows:
+```
+hawq-ambari-plugin
++-- README.md
++-- build.properties
++-- pom.xml
++-- src
++-- main
++-- resources
++-- services
+¦   +-- HAWQ
+¦   ¦   +-- metainfo.xml
+¦   +-- PXF
+¦   +-- metainfo.xml
++-- utils
++-- add-hawq.py
+```
+
+### build.properties
+[build.properties](build.properties) contains properties required for 
building the plugin.
+
+### metainfo.xml
+[metainfo.xml](src/main/resources/services/HAWQ/metainfo.xml) contains the 
metadata about the service. The metainfo.xml specifies that the service 
definition is to be inherited from Ambari common-services. HAWQ and PXF 
common-services code can be found under [Apache Ambari 
repository](https://github.com/apache/ambari/tree/trunk/ambari-server/src/main/resources/common-services/).
+
+### add-hawq.py
+[add-hawq.py](src/main/resources/utils/add-hawq.py) deploys HAWQ and PXF 
metainfo.xml files under the stack and adds the repositories to Ambari.
+
+
+## Building the plugin
+***Build Environment***: centos6 is the typical operating system used for 
building.
+
+Properties specified in the [build.properties](build.properties) file:
+
+| Property | Description | Value |
+| --- | --- | --- |
+| hawq.release.version | Release version of HAWQ | 2.0.1 |
+| hawq.common.services.version | HAWQ common services code in Ambari to be 
inherited | 2.0.0 |
+| pxf.release.version | Release version of PXF | 3.0.1 |
+| pxf.common.services.version | PXF common services code in Ambari to be 
inherited | 3.0.0 |
+| hawq.repo.prefix | Repository name for HAWQ core repository  | hawq |
+| hawq.addons.repo.prefix | Repository name for HAWQ Add Ons repository  | 
hawq-add-ons |
+| repository.version | Repository Version to be used in repository 
information | 2.0.1.0 |
+| default.stack | Default stack under which, metainfo.xml and repositories 
have to be added | HDP-2.4 |
+
+To build the rpm for hawq-ambari-plugin, change the 
[build.properties](build.properties) file with the required parameters and run 
```mvn install``` command under hawq-ambari-plugin directory:
+```
+$ pwd
+incubator-hawq/contrib/hawq-ambari-plugin
+$ mvn install

There is no major problem with putting these parameters back in the pom.xml

I find it to be cleaner and better managed as a separate file. 

For the commercial release, a different set of build.properties can be 
used. It is easier to use a new build.properties file rather than updating the 
pom.xml or explicitly specify overrides for each parameter in the mvn command 
during the build process. 

Do you still want it back in the pom.xml?

+# HAWQ Ambari Plugin
+
+hawq-ambari-plugin helps users install HAWQ and PXF using Ambari.
+
+To ensure that Ambari recognizes HAWQ and PXF as services that can be 
installed for a specific stack, the following manual steps are required:
+ * Add HAWQ and PXF metainfo.xml files (containing metadata about the 
service) under the stack to be installed.
+ * Add repositories where HAWQ and PXF rpms reside, so that Ambari can use 
it during installation. This requires updating repoinfo.xml under the stack 
HAWQ and PXF is to be added.
+ * If a stack is already installed using Ambari, add repositories to the 
existing stack using the Ambari REST API.
+
+
+## Source Code
+Source code directory structure of the hawq-ambari-plugin is as follows:
+```
+hawq-ambari-plugin
++-- README.md
++-- build.properties
++-- pom.xml
++-- src
++-- main
++-- resources
++-- services
+¦   +-- HAWQ
+¦   ¦   +-- metainfo.xml
+¦   +-- PXF
+¦   +-- metainfo.xml
++-- utils
++-- add-hawq.py
+```
+
+### build.properties
+[build.properties](build.properties) contains properties required for 
building the plugin.
+
+### metainfo.xml
+[metainfo.xml](src/main/resources/services/HAWQ/metainfo.xml) contains the 
metadata about the service. The metainfo.xml specifies that the service 
definition is to be inherited from Ambari common-services. HAWQ and PXF 
common-services code can be found under [Apache Ambari 
repository](https://github.com/apache/ambari/tree/trunk/ambari-server/src/main/resources/common-services/).
+
+### add-hawq.py
+[add-hawq.py](src/main/resources/utils/add-hawq.py) deploys HAWQ and PXF 
metainfo.xml files under the stack and adds the repositories to Ambari.
+
+
+## Building the plugin
+***Build Environment***: centos6 is the typical operating system used for 
building.
+
+Properties specified in the [build.properties](build.properties) file:
+
+| Property | Description | Value |
+| --- | --- | --- |
+| hawq.release.version | Release version of HAWQ | 2.0.1 |
+| hawq.common.services.version | HAWQ common services code in Ambari to be 
inherited | 2.0.0 |
+| pxf.release.version | Release version of PXF | 3.0.1 |
+| pxf.common.services.version | PXF common services code in Ambari to be 
inherited | 3.0.0 |
+| hawq.repo.prefix | Repository name for HAWQ core repository  | hawq |
+| hawq.addons.repo.prefix | Repository name for HAWQ Add Ons repository  | 
hawq-add-ons |
+| repository.version | Repository Version to be used in repository 
information | 2.0.1.0 |
+| default.stack | Default stack under which, metainfo.xml and repositories 
have to be added | HDP-2.4 |
+
+To build the rpm for hawq-ambari-plugin, change the 
[build.properties](build.properties) file with the required parameters and run 
```mvn install``` command under hawq-ambari-plugin directory:
+```
+$ pwd
+incubator-hawq/contrib/hawq-ambari-plugin
+$ mvn install

Nice catch. Will update the build command.
