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.
> change dfs.datanode.domain.socket.path to dfs.domain.socket.path

> {{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.
