Subject [jira] [Commented] (MAPREDUCE-3239) Use new createSocketAddr API in MRv2 to give better error messages on misconfig
Date Fri, 21 Oct 2011 18:18:32 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-3239?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13132888#comment-13132888
] 

Todd Lipcon commented on MAPREDUCE-3239:
----------------------------------------

The test failure is due to a test that sets the RM address to "local" and makes sure it throws
an exception. But this patch has a change that allows you to specify just a hostname without
a port, and it will use the default port, so "local" is interpreted as "local:8040". I think
the patch is correct here, and we should change the test to give an invalid address like "invalid:invalid"
which would fail parsing. Do you agree, Mahadev?

> HADOOP-7749 added a NetUtils call which will include the configuration name as part of
the exception message. This is handy if you accidentally specify some invalid string, or forget
to specify a required parameter. This JIRA is to make MR2 use the new API.
