Chen He commented on HADOOP-10660:
----------------------------------
The unit test failure is caused by hostname is null. NetUtils applies
normalizeHostNames() to a list of string. For each string, NetUtils applies
normalizeHostName() which actually return
InetAddress.getByName(string).getHostAddress();
I did not find relationship between this error and my patch.
> GraphiteSink should implement Closeable

> socket when it is stopped.
