    Hi Manish,
    I found the following that might help from a different post:

    http://hortonworks.com/community/forums/topic/install-ok-but-trouble-validating/

    The above appears to be due to a Powershell security issue when installing HDP on standalone (non-domain member) Windows servers. There may be a step or two missing in the installation instructions in section 5.5. I added each machine to a domain, set Group Policy for the domain (as directed by section 5.6 and the above issue disappeared. Also, I installed version 1.3 and replicated the behavior.

    Regards,
    Robert

    Hi Manish,

    start_remote_hdp_services are the services which you installed on other nodes. For example if you have services installed on Node1 2 and 3. If you run start_local_hdp_services on Node1 then the services installed on Node1 will start. If you run start_remote_hdp_services then the services on Node 2 and 3 will start.
    This is dependent on the configuration of the cluster and configuration of the batch file.

    It is not a HDP ‘mode’ as such.

    Thanks

    Dave
