Subject [jira] [Commented] (HDFS-4416) change dfs.datanode.domain.socket.path to dfs.domain.socket.path
Date Thu, 17 Jan 2013 23:02:12 GMT

    [ https://issues.apache.org/jira/browse/HDFS-4416?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13556701#comment-13556701
] 

Todd Lipcon commented on HDFS-4416:
-----------------------------------

- can you change the conf.get() calls to conf.getTrimmed()? We've often seem issues where
people end up with extra whitespace in their configs, and end up with files like "/home/hdfs/
/foo/bar" (literal whitespace dirs).

Otherwise lgtm.

> {{dfs.datanode.domain.socket.path}} is used by both clients and the DataNode, so it might
be best to avoid putting 'datanode' in the name.  Most of the configuration keys that have
'datanode' in the name apply only to the DN.
> Also, should change __PORT__ to _PORT to be consistent with _HOST, etc.
