> Server listener binds to wrong IP address for domain name given
> ---------------------------------------------------------------
>
> Key: HADOOP-6429
> URL: https://issues.apache.org/jira/browse/HADOOP-6429
> Project: Hadoop Common
> Issue Type: Bug
> Components: ipc
> Affects Versions: 0.22.0
> Environment: Ubuntu Linux, kernel 2.6.24-25-server, x86_64
> architecture. Java 1.6.0., OpenJDK. Server has 4 physical Ethernet cards,
> configured as follows: {{eth0}} is assigned an IP address {{external-ip}}.
> {{eth1}}-{{eth3}} are bonded as {{bond0}}, which is assigned an IP address
> {{internal-ip}}. This server has two dns entries: {{external-dns}} which
> resolves to {{external-ip}} and {{internal-dns}} which resolves to
> {{internal-ip}}.
> Reporter: Eric Anderson
>
> High-level:
> In my configuration files, I specifiy:
> {code:xml}
> <property>
> <name>fs.default.name</name>
> <value>hdfs://{{internal-dns}}:8020</value>
> </property>
> {code}
> The name node server binds to address {{external-ip}}:8020, while all the
> data nodes try to connect to {{internal-ip}}:8020, and nothing works.
> Low-level: I've traced this down as far as {{org.apache.hadoop.ipc.Server}},
> private class {{Listener}}.
> {code:java}
> /** Listens on the socket. Creates jobs for the handler threads*/
> private class Listener extends Thread {
>
> private ServerSocketChannel acceptChannel = null; //the accept channel
> private Selector selector = null; //the selector that we use for the
> server
> private InetSocketAddress address; //the address we bind at
> private Random rand = new Random();
> private long lastCleanupRunTime = 0; //the last time when a cleanup
> connec-
> //-tion (for idle connections) ran
> private long cleanupInterval = 10000; //the minimum interval between
> //two cleanup runs
> private int backlogLength = conf.getInt("ipc.server.listen.queue.size",
> 128);
>
> public Listener() throws IOException {
> address = new InetSocketAddress(bindAddress, port);
> LOG.info("in Server/Listener. bindAddress=" + bindAddress + ",
> address="+address); //Added by EA for testing
> // Create a new server socket and set to non blocking mode
> acceptChannel = ServerSocketChannel.open();
> acceptChannel.configureBlocking(false);
> // Bind the server socket to the local host and port
> bind(acceptChannel.socket(), address, backlogLength);
> port = acceptChannel.socket().getLocalPort(); //Could be an ephemeral
> port
> {code}
> The problem seems to be in the line {code}address = new
> InetSocketAddress(bindAddress, port);{code}. bindAddress contains the DNS
> name of the *internal* interface, but address comes out with the IP address
> of the *external* interface.
