+ ''2.1 [[#30|When writing a New InputFormat, what is the format for the array of string returned
by InputSplit\#getLocations()?]]''

+ It appears that DatanodeID.getHost() is the standard place to retrieve this name, and the
machineName variable, populated in DataNode.java\#startDataNode, is where the name is first

is not available, DNS.getDefaultHost is used instead.
