    I have CentOS 6.3 virtual machine running on Hyper-V and I am attempting a single machine HDP installation. I believe that I have followed the pre-deployment steps very carefully but my deployment during the HMC steps fail when I am reaching the final step of the cluster install.

    As per suggestion I ran the check script and uploaded the file as test7.aplhive3.out

    Any suggestions on what I am missing or trouble-shooting are highly welcome.

    Thanks,
    - Thomas

    Excellent, after making the change the install process completes just fine and all the services are running.

    Thanks,

    Thomas,
    you hit well known problem.
    HMC discovers mount points incorrectly and as a result, attempting to create directories in the device file, instead of real mount point:
    mkdir -p /dev/mapper/vg_aplhive3-lv_root/hadoop/hdfs/namenode]/returns (err): change from notrun to 0 failed: mkdir -p /dev/mapper/vg_aplhive3-lv_root/hadoop/hdfs/namenode returned 1 instead of one of [0]

    Please, rerun installation and in the mount-point selection page uncheck /dev/mapper locations and type “/” (no quotes!!!) in the text field.

    Thank you!
    Sasha
