works with centos-6 but not centos-7 about bdutil HOT 1 OPEN

You may find more useful errors further down the debuginfo.txt; that particular error you saw may be a red herring sometimes in a debuginfo.txt if it occurs while waiting on initial sshability. Alternatively, if that's the only error you see in debuginfo.txt, it may be a transient error being unable to SSH onto the VM.

I did manage to repro a failed ambari deployment on centos-7; my error is a bit different:

dhuo-ambari-w-1:    error reading information on service iptables: No such file or directory

This occurs inside ambari-setup.sh, on the line chkconfig iptables off:

[root@dhuo-ambari-w-1 dhuo]# chkconfig iptables off
error reading information on service iptables: No such file or directory

In general, CentOS 7 is not listed as an officially-supported OS for Ambari 1.7.0 and some discussion on StackOverflow seems to indicate that it wouldn't be expected to work even if the iptables command in this case is worked around. @seanorama could perhaps comment more on the timeline for official CentOS 7 support.
