Hi All, Need to propose a feature for Ambari to support hybrid cluster. Hybrid cluster means having multiple hosts with different OS architectures. Examples as given below: 1. Set up Ambari cluster with 2 RHEL-7 x86 and 1 RHEL-7 Power hosts. 2. Add a RHEL-7 Power host to existing Ambari cluster of RHEL-7 x86 hosts and vice versa.
We have setup a Hybrid cluster manually with x86_64 and ppc64le hosts with some workarounds and were able to run Hadoop jobs successfully. Workarounds include: 1. Setting up yum repos for Ambari, HDP & HDP-UTILS. 2. Use of same JAVA_HOME on all the hosts (note that ppc host will have different path for default JDK as that of x86). JIRA has been already created which links to AMBARI-21674 (Ambari to support Hybrid cluster). Hope to get some comments with questions and suggestions about it. We have been exploring the design and code changes for some time now. Regards, Yussuf Shaikh
