[jira] Commented: (HADOOP-4744) Wrong resolution of hostname and port

["Steve Loughran (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HADOOP-4744?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12706788#action_12706788 ] 

Steve Loughran commented on HADOOP-4744:
----------------------------------------

Could the new patch throw an exception instead? As the hadoop-4744-new.patch did? That means that however the TT is executed -and that included under junit- the failure is caught at the right layer of code, instead of having methods acrosss the codebase deciding when to exit the JVM.

> I noticed the following for one of the hosts in a cluster:
> 1. machines.jsp page resolves the http address as just "http://hostname" (which doesn't work). It doesnt put the port number for the host. Even if I add the port number manually in the URI, the  task tracker page does not come up. 
> 2. All the tasks(both maps and reduces) which ran on the machine ran successfully. But tasklogs cannot be viewed, because port-number is not resolved. ( same problem as in (1)).
> 3. The reducers waiting for maps ran on that machine fail with connection failed errors saying the hostname is 'null'.
