        Hello Arpit Agarwal

        hope you are talking about following correction..Please correct me if I am wrong.

        <property>
        <name>dfs.namenode.rpc-bind-host</name>
        <value>0.0.0.0</value> --> should be hostname

        Hi Brahma, this is not what I meant. 0.0.0.0 is correct for the bind-host keys.

        I meant we should encourage administrators to use hostnames in master/slave configuration files over using IP addresses.

        Arpit Agarwal Thanks a lot for your inputs. Finally Going to put like "It is strongly recommended that to use hostnames in master/slave configuration files over using IP addresses".
