Subject [jira] [Commented] (HDFS-4320) Add a separate configuration for namenode rpc address instead of only using fs.default.name
Date Wed, 18 Sep 2013 00:27:51 GMT

    [ https://issues.apache.org/jira/browse/HDFS-4320?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13770209#comment-13770209
] 

Chuan Liu commented on HDFS-4320:
---------------------------------

We need to reopen this JIRA for 2.0/trunk code base. I think the original trunk patch did
have some problems. We should use the existing key "dfs.namenode.rpc-address" instead of creating
the new key "dfs.namenode.address".

> When NameNode starts up, it tries to find out its address by looking at the fs.default.name
configuration key instead of using its own keys. This breaks scenarios where we try to configure
a Hadoop cluster that uses a different default file system than DFS, but still try to prop
up namenode and datanode services as a secondary file system.
