Any thoughts on this approach? If everyone is happy with this, I'll have a look
at implementing it.
> No retry on DNS lookup failure
> ------------------------------

> Key: CURATOR-229
> URL: https://issues.apache.org/jira/browse/CURATOR-229
> Project: Apache Curator
> Issue Type: Bug
> Components: Framework
> Affects Versions: 2.7.0
> Reporter: Michael Putters
>
> Our environment is setup so that host names (rather than IP addresses) are
> used when registering services.
> When disconnecting a node from the network, it will attempt to reconnect and
> - in order to do this - attempts to resolve a host name, which fails (since
> we have no network connectivity and a DNS server is used).
> It appears this type of exception is not retryable, and the node simply gives
> up and never reconnects, even when the network connectivity is back.
> Is this the expected behavior? Is there any way to configure Curator so that
> this type of exception is retryable? I had a look at
> {{CuratorFrameworkImpl.java}} around line 768 but there doesn't seem to be
> anything configurable.
> If this is not the expected behavior (or if it is but you don't mind making
> it configurable), I should be able to provide a patch via a pull request.
