WARNING: this is a workaround and does not mean is a certifiable solution from Hortonworks. In certain scenarios, customers are required to run client and services on different OS versions and flavors. I will only cover clients for Pig and Hive, certainly this procedure can be applied to services but it's more involved. It is advised that you contact Hortonworks support if you go down this path. Setup scenario: 3 node Ubuntu 12.04 cluster with HDP 2.4.2 and Ambari 2.2.2.0 1 node Centos 6 and no Ambari. on the centos6 node, download and install Java, preferably the same as on other nodes. I followed this document to install Oracle JDK 8 as that's what is running on my Ubuntu cluster. https://www.digitalocean.com/community/tutorials/how-to-install-java-on-centos-and-fedora on the centos6 node, download the hdp repo wget http://public-repo-1.hortonworks.com/HDP/centos6/2.x/updates/2.4.2.0/hdp.repo
cp hdp.repo /etc/yum.repos.d
yum install hadoop pig hive-hcatalog hive-webhcat tez copy the /etc/hadoop/conf, /etc/pig/conf, /etc/tez/conf and /etc/hive/conf from the cluster to your new node into the same directories as on the other nodes. scp -r /etc/hadoop root@192.168.56.111:
scp -r /etc/hive root@192.168.56.111:
scp -r /etc/pig root@192.168.56.111:
scp -r /etc/tez root@192.168.56.111:
move the conf dir to it's designated directories: cp -r hadoop/conf /etc/hadoop/
cp -r hive/conf /etc/hive/
cp -r pig/conf /etc/pig/
cp -r tez/conf /etc/tez/
now you should be able to access hdfs, pig, hive and tez from new node. you can run validation of your environment based on the manual install guide http://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.4.2/bk_installing_manually_book/content/ref-1a378094-a4fb-4348-bd9e-2eebf68c2e1e.1.html [root@centos6 ~]# cat test.txt

you can do the same with pig using http://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.4.2/bk_installing_manually_book/content/validate_the_installation_pig.html [root@centos6 ~]# hdfs dfs -put /etc/passwd .
[root@centos6 ~]# pig -x tez
grunt> A = load 'passwd' using PigStorage(':');

If you were to install other clients, you'd follow the same hdp manual install/upgrade guides. For services installation, it will be a bit more involved but doable. Conclusion: This is certainly not a recommended approach but sometimes it's a necessary evil. Same should work with Apache releases not from HDP. I was certainly able to run Bigtop packages against HDP.
