Proxy error while starting services in Ambari 2.2

[#1]

I'm trying to set up a single-node Hadoop cluster (HDP2.3 version) using Ambari 2.2 in Eucalyptus environment.

I have used Private IP address as recommended while registering the VM's (RHEL 6.5) with Ambari.

When I tried to bring up Hadoop services (MR2, Hive, Yarn) , I'm getting the below error:

 <LI id=L_11001_11>Error Code 11001: Host not found
<LI id=L_11001_12>Background: This error indicates that
the gateway could not find the IP address of the website you are trying to
access. This is usually due to a DNS-related error.
<LI id=L_11001_13>Date: 2/9/2016 5:57:11 AM [GMT]
<LI id=L_11001_14>Server: FIESPRX004.xxx.net
<LI id=L_11001_15>Source: DNS error
</UL>

Please have a look at dns configuration for Eucalyptus

@Phoncy Joseph Are you getting this error in the browser?

Thanks for the response. I have set no proxy for local addresses in the host machine using export no_proxy from the command line. Below is the command that fails while starting the service:

resource_management.core.exceptions.Fail: Execution of 'curl -sS -L -w '%{http_code}' -X GET 'http://fqdn:50070/webhdfs/v1/app-logs?op=GETFILESTATUS&user.name=hdfs'' returned status_code=502.

@Phoncy Joseph Bad Gateway request. Are you able to run this? telnet fqdn 50070 ?

Yes, it says connected.

@Phoncy Joseph Let's check if this shed more light http://www.cyberciti.biz/faq/linux-unix-set-proxy-environment-variable/

Setting no proxy for the fqdn in /etc/profile solved the issue. Thanks.

what is your JDK version with Ambari 2.2? I'm wondering if you're hitting this https://issues.apache.org/jira/browse/AMBARI-14778 @Phoncy Joseph
