Adding RPMs

One of the easiest ways to add functionality and customization is to add RPMs to the distribution. There are couple ways to do this - this is the no-brainer, gottagetitworkingrightnow, easy way.

(If you want a bunch of RPMs and they live in a repository somewhere, go to Creating Simple Pallets)

Adding RPMs

Download the RPM for the application you want.

Add the RPM(s) to:

/export/stack/contrib/default/1.0/x86_64/RPMS/

And then do:

# stack create distribution

If you want to add them on the fly, i.e. you don't want to reinstall your machines then do:

# stack run host "yum clean all && yum -y install <rpmname>" \*

on the backend nodes.

They're also available during installs if you add the name of the package to package tags in the extend-backend.xml.

So in /export/stack/site-profiles/default/1.0/nodes/extend-backend.xml

<package>myrpmname</package>

Before any <post> </post> tags.

Example

We frequently have people who want to add machines to an already existing Hadoop cluster elsewhere in their organization. All they want is the Cloudera/Ambari/Hadoopy-thingy agent added to the machines that they've installed with the right partition and storage set-up.

So do something like this:

% Download the RPM for the application you want.

(We're using Cloudera 5 in this example because that's what's in my browser history already.)

Go to:

http://archive.cloudera.com/cm5/redhat/6/x86_64/cm/5/RPMS/x86_64/

Copy the link address. (Right click?) on cloudera-manager-agent-5.4.5-1.cm545.p0.5.el6.x86_64.rpm.

% On the frontend:

# cd /export/stack/contrib/default/1.0/x86_64/RPMS/
# wget http://archive.cloudera.com/cm5/redhat/6/x86_64/cm/5/RPMS/x86_64/cloudera-manager-agent-5.4.5-1.cm545.p0.5.el6.x86_64.rpm

% Recreate the distribution

# stack create distribution

Now it's available.

% To install it immediately:

# stack run host "yum clean all && yum -y install cloudera-manager-agent"

% To add it on install/reinstall.

Add it to /export/stack/site-profiles/default/1.0/nodes/extend-backend.xml:

Before any <post> </post> tags, add a package tag:

<package>cloudera-manager-agent</package>

% Recreate the distribution to get the changes to extend-backend.xml

# stack create distribution

% Install/reinstall machines.

# stack set host boot backend action=install
# stack run host "reboot"

* Please note the RPM name is usually the text before any versions of the full package name. So cloudera-manager-agent-5.4.5-1.cm545.p0.5.el6.x86_64.rpm is "cloudera-manager-agent." If you don't know the correct name, do any of the following:

# yum info cloudera-manager-scm*
(Or, on the file you downloaded)
# rpm -qpl cloudera-manager-agent* 
# rpm -qp --qf  %{NAME} cloudera-manager-agent-5.4.5-1.cm545.p0.5.el6.x86_64.rpm **

** Old guy command.
