Subject [jira] Commented: (HDFS-771) NameNode's HttpServer can't instantiate InetSocketAddress: IllegalArgumentException is thrown
Date Sat, 14 Nov 2009 02:19:39 GMT

    [ https://issues.apache.org/jira/browse/HDFS-771?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12777806#action_12777806
] 

Konstantin Boudnik commented on HDFS-771:
-----------------------------------------

After all it seems to be a race condition in the Jetty, e.g. (NameNode:367)
{noformat}
    this.httpServer.start();
{noformat}

Appropriate log file
{noformat}
2009-11-13 07:02:04,605 INFO  http.HttpServer (HttpServer.java:start(432)) - Port returned
by webServer.getConnectors()[0].getLocalPort() before open() is -1. Opening the listener on
0
2009-11-13 07:02:04,606 INFO  http.HttpServer (HttpServer.java:start(437)) - listener.getLocalPort()
returned 37817 webServer.getConnectors()[0].getLocalPort() returned 37817
2009-11-13 07:02:04,607 INFO  http.HttpServer (HttpServer.java:start(470)) - Jetty bound to
port 37817
2009-11-13 07:02:04,607 INFO  mortbay.log (?:invoke0(?)) - jetty-6.1.14
2009-11-13 07:03:04,231 INFO  mortbay.log (?:invoke0(?)) - Started SelectChannelConnector@localhost:37817
{noformat}

And the this code is executed (NameNode:370-371)
{noformat}
    // The web-server port can be ephemeral... ensure we have the correct info
    infoPort = this.httpServer.getPort();
    this.httpAddress = new InetSocketAddress(infoHost, infoPort);
{noformat}
and {{this.httpServer.getPort();}} returns -1 as the infoPort value

I'll try to work out a minimal test case to reproduce this problem, however it might be hard.
