Ivan Kelly commented on BOOKKEEPER-618:
---------------------------------------
I've seen this before, with servers created in a VPS environment. I recall
hbase actually suffering from the same thing, but they could have fixed it
since then. This was with 0.92.0.
> Better resolution of bookie address
> -----------------------------------
>
> Key: BOOKKEEPER-618
> URL: https://issues.apache.org/jira/browse/BOOKKEEPER-618
> Project: Bookkeeper
> Issue Type: Improvement
> Components: bookkeeper-server
> Affects Versions: 4.2.1
> Reporter: Bryan Beaudreault
> Priority: Minor
> Fix For: 4.3.0
>
>
> Bookie#getBookieAddress uses the following code:
> {code:title=Bookie.java}
> /**
> * Return the configured address of the bookie.
> */
> public static InetSocketAddress getBookieAddress(ServerConfiguration conf)
> throws UnknownHostException {
> return new InetSocketAddress(InetAddress.getLocalHost()
> .getHostAddress(), conf.getBookiePort());
> }
> {code}
> This code is subject to the contents of one's /etc/hosts file, in that if
> they have an entry like {{127.0.0.1 myhostname}}, this method will return the
> same 127.0.0.1 address on all bookie servers. This causes conflicts due to
> the way bookies register in zookeeper.
> There should be an optional bk_server.conf setting to allow one to select
> their preferred network interface to use for the bookie. Then you could use
> something like
> {{NetworkInterface.getByName(PREFERRED_INTERFACE).getInetAddresses()}}
> instead. This method is not effected by the /etc/hosts.
> An alternative method of registering the bookie that does not rely on the
> local address would be another possible solution, such as using the DNS like
> other apache projects (hbase).
