Hi Umang, Tal,

we have received your complain about the service related to the
following URL:

http://storage.dit.upm.es:14000/webhdfs/v1/user/umangsuthar/testdir?op=MKDIRS&user.name=umangsuthar

We have tested the service with your credentials and all is working as
expected. The logs reflect that our firewall is allowing the traffic and
that the connections are flowing seamlessly, apart of the limit of 10
connections per second for that port (that has not been reached).

We suspect that the problem is outside our network, and we suggest you
to check with any intermediate network providers that you have, because
we are receiving traffic for the service from outside our network
without any problems.

If your investigations lead to us again, please, provide us with the
client IP and the hours and timing you are testing the service, in order
we can check the logs for your network.

Thank you very much and have a nice weekend.

Omar
