Hi Yusaku, There is a different number of VMDK in the different virtual machine. So mount points are different in these virtual machines.

It would be best to not have 100 different configs for 100 different hosts. Is there anyway you can use the same mount points for these hosts? Typically, you may have several classes of machines (say, different number of disks).

I think the host_group is the group which includes the same attributes hosts. Maybe there is a host or more than one in a host_group. So if I want to set configurations for each host. How to do? I think it isn't convenient to set configurations to each host when a host_group has many hosts.For example, { "blueprint": "multi-node-hdfs-yarn", "host_groups":[ { "name": "master", "hosts": [ { "fqdn": "c6401.ambari.apache.org<https://urldefense.proofpoint.com/v1/url?u=http://c6401.ambari.apache.org&k=oIvRg1%2BdGAgOoM1BIlLLqw%3D%3D%0A&r=XFPetyuh5lGv3twiMNs7nw%3D%3D%0A&m=zr3ckRNJEVJ%2B7zQShmUFM9vYstWx6%2Fe%2B0VI7WGP7RIo%3D%0A&s=f9b31ec62449af463e2dee594973c5ff1797187ac253ba66f7dac46f8c0594bc>" } ] }, { "name": "slaves", "hosts": [ { "fqdn": "c6402.ambari.apache.org<https://urldefense.proofpoint.com/v1/url?u=http://c6402.ambari.apache.org&k=oIvRg1%2BdGAgOoM1BIlLLqw%3D%3D%0A&r=XFPetyuh5lGv3twiMNs7nw%3D%3D%0A&m=zr3ckRNJEVJ%2B7zQShmUFM9vYstWx6%2Fe%2B0VI7WGP7RIo%3D%0A&s=6a60e82c0bc013fceb7671c67c8addfc8528a6e8470498fa68604562431785f3>" }, { "fqdn": "c6403.ambari.apache.org<https://urldefense.proofpoint.com/v1/url?u=http://c6403.ambari.apache.org&k=oIvRg1%2BdGAgOoM1BIlLLqw%3D%3D%0A&r=XFPetyuh5lGv3twiMNs7nw%3D%3D%0A&m=zr3ckRNJEVJ%2B7zQShmUFM9vYstWx6%2Fe%2B0VI7WGP7RIo%3D%0A&s=469c66697be63cdeab1006495edf62f78e72db0072a176e4a96bd9d961ddf788>" } ] } ] } The host_groups slaves has two hosts.

You can set configurations at the blueprint level (to apply to all host_groups) and you can also set configurations in the host_groups element to set configurations for that host_group. Will that help? Or will it just mean you will have to have a host_group that you have to apply per host? https://cwiki.apache.org/confluence/display/AMBARI/Blueprints#Blueprints-Configurations<https://urldefense.proofpoint.com/v1/url?u=https://cwiki.apache.org/confluence/display/AMBARI/Blueprints%23Blueprints-Configurations&k=oIvRg1%2BdGAgOoM1BIlLLqw%3D%3D%0A&r=XFPetyuh5lGv3twiMNs7nw%3D%3D%0A&m=EfpGl9vWkh%2FuFYOC%2FWIgKw9XBLClivVRI1LFsC2njqs%3D%0A&s=3b6c5134ae1180ec8287000ba557ef4b0030e02634e6e5fccc15feed9f094d67> On Thu, Jun 5, 2014 at 12:58 AM, Qing Chi 79624 <c...@vmware.com<mailto:c...@vmware.com>> wrote: Hi guys, I want to use specific data dir on each host.
