I see the repo URL you are using as

http://centos/yum/HDP/centos6/2.x/updates/2.1.10.0/repodata/repomd.xml

Here the host name is "http://centos". Can you please check if you have really configured this hostname in your "/etc/hosts" file?

Is that host name intended or by mistake?

Can you also search which repo file in your system has the hostname "centos"?

grep "http://centos"  /etc/yum.repos.d/*

.

If you have configured a custom HDP/Ambari repo then let us know if "http://centos" is it your custom repo host? If, yes then the mentioned hostname should be resolvable and reachable. A simple WGET can help in knowing if the mentioned URL is accessible or not ?

wget http://centos/yum/HDP/centos6/2.x/updates/2.1.10.0/repodata/repomd.xml

- If the URL is not accessible then it means wither your Custom Local repo (hosted on "centos") is not configured properly and not accessible.

(OR)

Some unwanted files with the mentioned host might be present in yoru "/etc/yum./repos.d" directory you might want to either fix them or remove them from the repos.d directory. and perform "yum clean all"

.
