Subject [jira] [Created] (HDFS-4269) DatanodeManager#registerDatanode rejects all datanode registrations from localhost in single-node developer setup
Date Wed, 05 Dec 2012 04:40:59 GMT
Chris Nauroth created HDFS-4269:
-----------------------------------

             Summary: DatanodeManager#registerDatanode rejects all datanode registrations
from localhost in single-node developer setup
                 Key: HDFS-4269
                 URL: https://issues.apache.org/jira/browse/HDFS-4269
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: namenode
    Affects Versions: trunk-win
            Reporter: Chris Nauroth
            Assignee: Chris Nauroth


HDFS-3990 is a change that optimized some redundant DNS lookups.  As part of that change,
{{DatanodeManager#registerDatanode}} now rejects attempts to register a datanode for which
the name has not been resolved.  Unfortunately, this broke single-node developer setups on
Windows, because Windows does not resolve 127.0.0.1 to "localhost".
