Some changes to make it work

[biemond]

Hi,

Great work,
I just made the following changes to make it work

params.pp

Commented out
include java::params
and just set
$java_home = $::hostname ? {
default => "/usr/java/jdk1.7.0_09",
}

also for hostnames with domain name , I had to use ""
$master = $::hostname ? {
default => "devagent1.alfa.local",
}
$slaves = $::hostname ? {
default => ["devagent1.alfa.local","devagent2.alfa.local","devagent3.alfa.local"]
}

init.pp

Commented out
include hadoop::master
include hadoop::slave

for exec I set the exec path
$execPath = '/usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/sbin:'

exec { "untar hadoop-${hadoop::params::version}.tar.gz":
path => $execPath,
command => "tar -zxf hadoop-${hadoop::params::version}.tar.gz",

remove File["java-app-dir"] require in
exec { "${hadoop::params::hadoop_base}/hadoop-${hadoop::params::version}/bin/hadoop namenode -format":

Result

Then it works perfectly

thanks Edwin
