Examples with ServerError org.apache.cassandra.stargate.transport.ServerError used on opensource projects

Example 1 with ServerError

use of org.apache.cassandra.stargate.transport.ServerError in project stargate by stargate.

the class ProxyProtocolQueryInterceptor method resolveAllPeers.

@SuppressWarnings("NonAtomicOperationOnVolatileField")
private void resolveAllPeers() {
    if (!Strings.isNullOrEmpty(proxyDnsName)) {
        try {
            // This task runs asynchronously, so it does not have context about a particular client. We
            // can't predict if connections will be public or private, so resolve everything.
            // Note that this also generates events, so private clients will get events for public
            // addresses, and vice versa. This is not a problem because client drivers ignore events if
            // they don't recognize the address.
            publicPeers = resolvePeers(proxyDnsName, publicPeers);
            privatePeers = resolvePeers(internalProxyDnsName, privatePeers);
        } catch (UnknownHostException e) {
            throw new ServerError("Unable to resolve DNS for proxy protocol peers table", e);
        }

Example 2 with ServerError
