    HDP is not frozen, it moving forward and pretty fast.
    It officially supports RHEL6/CentOS6, you can go ahead and do your installation.

    Muhamed,
    it clearly said about the OS versions:

    Component Platforms
    Hortonworks Management Center (HMC) (1) Operating Systems
    RHEL / CentOS 5 (64-bit)
    RHEL / CentOS 6 (64-bit)
    Web Browsers
    Mozilla Firefox – Latest stable version (12 or later)

    Hadoop Components (2) Operating Systems (3)
    RHEL / CentOS 5 (64-bit)
    RHEL / CentOS 6 (64-bit)

    PLus, it define the list of the packages which should on an exact version:

    Check the dependencies on each host in the cluster using the yum info [dependency]command. Confirm the following are either not installed, or if installed, they are these versions.
    Name Dependency Version-Release
    Ruby ruby 1.8.5-24.el5
    Puppet puppet 2.7.9-2
    Ruby Rack rubygem-rack 1.1.0-2.el5
    Ruby Passenger rubygem-passenger 3.0.12-1.el5.centos
    Nagios nagios 3.0.12-1.el5.centos
    Nagios Plugins nagios-plugins 1.4.15-2.el5
    Nagios Common nagios-common 2.12-10.el5
    MySQL mysql 5.*

    There is not much more requirements.
    For example, “Basic Server” package is enough to be installed, plus compatibility libraries.
    Any additional dependencies will be installed during HMC installation.

    Thank you!
    Sasha

    In such case you have to remove installed ruby, the hmc will install correct version as a dependency.

    the ruby version 1.8.7.352 not installed in my OS
    the yum info get the information from base repo and its meaning the HMC will install thise version not the correct version
