Returns 127.0.0.1 at HostInterceptor
hi all, HostInterceptor obtains loopback address if there hasn't configure
for local server at /etc/hosts. Can we change the acquire method for local
IP. Currently, we are using 'InetAddress.getLocalHost().getHostAddress()'

Sure, StatisInterceptor is another choice if I want to transfer pre-defined
IP to each event. This is a proposal for right local IP. In my situation,
several Flume servers cannot be distinguished with IP no matter in HDFS or
monitoring system. What do you think if original HostInterceptor support
effective function?

Hi Denny,
What are your thoughts for improving this? Maybe you want to consider
submitting a patch?
If you know what the string you want to use is, you might also consider
using a StaticInterceptor.

Mike

Sorry to jump on this thread so late but you should be aware that getLocalHost() seems to have a nasty habit of throwing a HostNotFoundException on Java 7. I ran into this in Log4j 2 and had to write some code to deal with that when it happens. See http://blog.leon-rosenberg.net/2012/08/oracle-kills-getlocalhost-on-macos-x-in.html

Sounds good, Denny. Yes, please file a Jira and post a patch.

I have wrote some codes to resolve this problem for me, and I want to know
if someone also need this function to obtains actual IP. If it's useful for
others, I can post patch for it if necessary

The result of ' InetAddress.getLocalHost().getCanonicalHostName()' is
'localhost', what's your advice if I would like to distinguish the actual
IP of my several Flume servers?

Today, InetAddress.getLocalHost().getCanonicalHostName() is used if you
pass useIP = false to the interceptor config.

We could use InetAddress.getLocalHost().getCanonicalHostName() to get just
the IP, which I feel is good enough; a quick and dirty interceptor could be
built that substitutes certain names for their matching IP
('SubstitutionInterceptor'?) which would then work well with any other
header-replacement needs someone would need.
