Package hadoop-0.20 is trying to stop its services but hadoop-0.20-<service> are already and rightfully taking care of it

Package hadoop-0.20 is trying to stop its services but hadoop-0.20-<service> are already and rightfully taking care of it:

%preun
if [ "$1" = 0 ]; then

1. Stop any services that might be running
   for service in %
   Unknown macro: {hadoop_services}

   do
   service hadoop-$service stop 1>/dev/null 2>/dev/null || :
   done

This is causing this error:

[root@localhost test]# yum remove hadoop-0.20.noarch hadoop-0.20-conf-pseudo.noarch hadoop-0.20-datanode.noarch hadoop-0.20-debuginfo.x86_64 hadoop-0.20-doc.noarch hadoop-0.20-libhdfs.x86_64 hadoop-0.20-jobtracker.noarch hadoop-0.20-namenode.noarch hadoop-0.20-sbin.x86_64 hadoop-0.20-sbin.i386 hadoop-0.20-secondarynamenode.noarch hadoop-0.20-tasktracker.noarch
