Trying to establish a Hadoop cluster via Ambari 2.0, however failure occurs at installation phase. Here are failure logs from one of the datanodes:

I think the problem is here:
2015-05-12 16:21:44,698 - Downloading the file from http://localhost:8080/resources//UnlimitedJCEPolicyJDK7.zip
It tries to download from localhost, but I think it should be address of the namenode. Am I missing something?
