Using an int/long with a good hash makes document distribution uniform
on the ring, and thus makes it much easier for the master to assign
ranges to nodes.

For example, for a two node system the master could assign NodeA
hashes 0x00000000-0x7FFFFFFF and NodeB hashes 0x80000000-0xFFFFFFFF,
knowing nothing about the document ids.  How would this work if one
uses the String Ids?  Or did you mean represent the hash as a String?
