Subject [jira] [Commented] (HDFS-3688) Namenode loses datanode hostname if datanode re-registers
Date Fri, 20 Jul 2012 18:33:35 GMT

    [ https://issues.apache.org/jira/browse/HDFS-3688?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13419416#comment-13419416

Jason Lowe commented on HDFS-3688:
----------------------------------

Patch failed on trunk since it's only for 23.  Manually ran test-patch for this on branch-0.23,
here's the output:

{noformat}
-1 overall.  

    +1 @author.  The patch does not contain any @author tags.

    +1 tests included.  The patch appears to include 3 new or modified tests.

    +1 javadoc.  The javadoc tool did not generate any warning messages.

    +1 javac.  The applied patch does not increase the total number of javac compiler warnings.

    +1 eclipse:eclipse.  The patch built with eclipse:eclipse.

    +1 findbugs.  The patch does not introduce any new Findbugs (version ) warnings.

    +1 release audit.  The applied patch does not increase the total number of release audit
warnings.

    -1 core tests.  The patch failed these unit tests:
                  org.apache.hadoop.hdfs.TestDatanodeBlockScanner

    +1 contrib tests.  The patch passed contrib unit tests.
{noformat}

The test failure appears to be unrelated, and when I ran the test again manually it passed.
 I believe this test is known to have some races in it, see HDFS-2881.

> If a datanode ever re-registers with the namenode (e.g.: namenode restart, temporary
network cut, etc.) then the datanode ends up registering with an IP address as the datanode
name rather than the hostname.
