Subject [jira] [Created] (HDFS-3484) hdfs fsck doesn't work if NN HTTP address is set to 0.0.0.0 even if NN RPC address is configured
Date Thu, 31 May 2012 18:35:23 GMT
Aaron T. Myers created HDFS-3484:
------------------------------------

             Summary: hdfs fsck doesn't work if NN HTTP address is set to 0.0.0.0 even if
NN RPC address is configured
                 Key: HDFS-3484
                 URL: https://issues.apache.org/jira/browse/HDFS-3484
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: hdfs client
    Affects Versions: 2.0.0-alpha
            Reporter: Aaron T. Myers
            Assignee: Aaron T. Myers
            Priority: Minor


The default NN HTTP address is 0.0.0.0. Clients which need to connect to the HTTP address
(e.g. fsck and fetchImage) need an address which is actually resolvable, however. If the configured
NN HTTP address is set to 0.0.0.0, these clients should fall back on using the hostname configured
for the RPC address, with the port configured for the HTTP address.
