> With HADOOP-18628 in place, we perform InetAddress#getHostName in addition to InetAddress#getHostAddress, to save host name with IPC Connection object. When we perform InetAddress#getHostName, toString() of InetAddress would automatically print \{hostName}/\{hostIPAddress} if hostname is already resolved:
> {code:java}
> /**
>  * Converts this IP address to a {@code String}. The
>  * string returned is of the form: hostname / literal IP
>  * address.
>  *
>  * If the host name is unresolved, no reverse name service lookup
>  * is performed. The hostname part will be represented by an empty string.
>  *
>  * @return  a string representation of this IP address.
>  */
> public String toString() {
>     String hostName = holder().getHostName();
>     return ((hostName != null) ? hostName : "")
>         + "/" + getHostAddress();
> }{code}
>  
> For namenode audit logs, this means that when dfs client makes filesystem updates, the audit logs would also print host name in the audit logs in addition to ip address.
> In order to maintain the compatibility, the purpose of this Jira is to only let audit log retrieve IP address from InetAddress and print it.
