Thanks. Now I wanted to try this on Debian, and the component is missing from bigtop-utils. Do you need assistence to implement this?

> Puppet should be flexible in allowing arbitrary configuration name value pairs to be merged into a given site.xml file that was generated from a template.
> For example, the following could be included in site.yaml which would add a configuration entry for hadoop.tmp.dir in core-site.xml:
> {code}
> hadoop::common_hdfs::hadoop_core_site_overrides:
>   "hadoop.tmp.dir": "/mnt/var/lib/hadoop/tmp"
> {code}
> This could be implemented as a puppet custom-function taking in the output of template:
> {code}
>     file {
>       "/etc/hadoop/conf/core-site.xml":
>         content => merge_site(template('hadoop/core-site.xml'),  $hadoop_core_site_overrides)
>         require => [Package["hadoop"]],
>     }
> {code}
> Perhaps another approach would be to have site.xml templates be created from a single map of name value pairs. The merge would happen before the file content is generated from the template.
