+## Trafodion Installers
+
+* **install** - This is the current command-line installer. It installs a
server tarball
+ on an existing CDH or HDP Hadoop cluster.
+* **python-installer** - This is the new command-line installer, meant to
replace current
+ command-line installer. Likewise, installs server tarball on existing
CDH, HDP,
+ or APACHE cluster.
+* **ambari-installer** - This integrates with Ambari cluster manager, so
only applies to HDP.
+ In this case, trafodion server is installed via RPM. This is installed
on Ambari server as
+ a management pack. Trafodion can be included in the initial cluster
creation or added later.
+
+## Ambari Integration
+
+The Ambari MPack (management pack) is also packaged as an RPM, having a
dependency on ambari-server.
+Given a proper yum repo file, `traf_ambari` rpm
+can be installed directly and it pulls in ambari-server.
+If ambari-server is previously installed and running, it must be restarted
to pick up the Trafodion
+management pack.
+
+#### Packaging
+
+Part of Ambari's job is to set up yum repo files on each node in order to
install packages.
+The default URLs are for Hortonworks' public repos. But since your
custom-built Trafodion is
+not hosted there, you need to specify a URL for your local yum repo
server. To build that into
+the `traf_ambari` package, use make to specify value of `REPO_URL`.
+
+ `make package REPO_URL=http://my.repo.server/repo/...`

@svarnau, thanks for the explanation. It seems that traf-ambari rpm package
is customized with different REPO_URL, so everytime we install on a different
envionment, we have to build a new traf-ambari rpm to apply the new URL, is
that true?
Can we put this URL into ambari webpage so we can configure the URL from
there?
