    Problem with " domain name pointer"

    Hi, I am having difficulty in setup a Hadoop networks (with on some of my VPSs.

    The log shows:

    Detecting Cloudera Manager Server...
    BEGIN host -t PTR domain name pointer .
    END (0)
    using as scm server hostname
    BEGIN which python
    END (0)
    BEGIN python -c 'import socket; import sys; s = socket.socket(socket.AF_INET); s.settimeout(5.0); s.connect((sys.argv[1], int(sys.argv[2]))); s.close();' 7182
    Traceback (most recent ca

    ll last):

    File "", line 1, in
    IndexError: list index out of range
    END (1)
    could not contact scm server at :7182, giving up
    waiting for rollback request

    You can see the cause of failure domain name pointer .

    In other VPS, the problem is
    " domain name pointer".

    But cloudera said "" is not accessible.

    Could you please give some hints regarding network resolving?
