Subject [jira] Created: (HADOOP-3233) Handling of deprecated dfs.info.bindAddress and dfs.info.port
Date Thu, 10 Apr 2008 21:20:08 GMT
Handling of deprecated dfs.info.bindAddress and dfs.info.port
-------------------------------------------------------------

                 Key: HADOOP-3233
                 URL: https://issues.apache.org/jira/browse/HADOOP-3233
             Project: Hadoop Core
          Issue Type: Bug
          Components: dfs
    Affects Versions: 0.16.2
         Environment: Windows XP
            Reporter: Cagdas Gerede
            Priority: Minor


When checkpointing is triggered in Secondary name node, Secondary name node throws exception
while it tries to connect to Namenode's http server in the following two cases:

1) In hadoop-site.xml, if you put only dfs.http.address but not dfs.info.bindAddress and dfs.info.port
(Connection Refused Exception)

2) In hadoop-site.xml, if you put only dfs.info.bindAddress and dfs.info.port but not dfs.http.address
(SecondaryNameNode.getServerAddress line 148 throws exception since newAddrPort is null)

Temporary Solution: If you put dfs.http.address, dfs.info.bindAddress, and dfs.info.port,
then SecondaryNameNode successfully fetches the image and log from Namenode.
