Problem with ".in-addr.arpa domain name pointer"

Hi, I am having difficulty in setup a Hadoop networks (with http://cloudera.com) on some of my VPSs.

The log shows:

Detecting Cloudera Manager Server...
BEGIN host -t PTR 172.245.215.28
28.215.245.172.in-addr.arpa domain name pointer .
END (0)
using as scm server hostname
BEGIN which python
END (0)
/usr/bin/python
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

28.215.245.172.in-addr.arpa domain name pointer .

In other VPS, the problem is
"198.49.72.173.in-addr.arpa domain name pointer 198-49-72-173.static.dimenoc.com".

But cloudera said "198-49-72-173.static.dimenoc.com" is not accessible.

Could you please give some hints regarding network resolving?

Thanks
