emailed jonathan an http site to download data files that reproduce this
problem.
AssertionError happened on node 105 (see ring below), and according to the keys
shown in above exception, 105 is the primary for the key. ReplicationFactor =
3 so 102 and 103 are replicas, right? i can use the cassandra-cli to retrieve
the value on the key's replica nodes, just not on the primary node.
