Is "hadoop.tmp.dir" the same property with "mapred.system.dir" (i.e. this directory is in your default file system and must be accessible from both the client and server machines and is typically in HDFS) for the clustering? which directories should be in the public shared directories, and which ones could be in the local default file system in the case of clustering? "hadoop-default.xml" is a typical example for the single node, any typical example for the clustering case?
