Ivan Kelly commented on BOOKKEEPER-66:
--------------------------------------

The check should exist in bookkeeper-server/bin/bookkeeper & hedwig-server/bin/hedwig also as in the hadoop solution. Otherwise the user would see that tests are all passing, but for some reason, the actual system would not work.

> On some linux boxes that run a dual IPv6-IPv4 network stack, with IPv6 enabled (e.g. debian-based), there is an issue with some java programs, preventing network connections.
> This results in "org.apache.zookeeper.KeeperException$ConnectionLossException: KeeperErrorCode = ConnectionLoss for /ledgers" in BookieZKExpireTest test (for instance) but is actually due to a previous "java.net.NoRouteToHostException: Network is
> unreachable" issue.
> I could reproduce this on a debian 6 for instance, and the issue is similar another one detailed in a Hadoop ticket: https://issues.apache.org/jira/browse/HADOOP-6056
> We should make sure IPv4 is used for builds so that one can build bookkeeper out of the box, without configuration changes to the OS.
