> I started a 3 node cluster with RF=3 and loaded about 3M keys into it.  I proceeded to bootstrap a 4th node and it completed.  Upon performing a read test, I found that  two nodes could find all keys, and two nodes could find none, depending upon which machine I queried.  Here is the ring output:
> Address       Status     Load          Range                                      Ring

> Token 0 was the newly bootstrapped node.  Tokens 127605887595351923798765477786913079296 and 85070591730234615865843651857942052864 were able to read all keys, the other two nodes were not.
