> Example [here|http://cassci.datastax.com/job/cassandra-2.2_dtest/369/testReport/junit/topology_test/TestTopology/simple_decommission_test/].
> {{SizeEstimatesRecorder}} can race with decommission when it tries to get the primary ranges for a node.
> This is because {{getPredecessor}} in {{TokenMetadata}} hits an assertion if the token is no longer in {{TokenMetadata}}.
> This no longer occurs in 3.0 because this assertion has been removed and replace with different data.
> In both cases, the relationship between the set of tokens in {{getPrimaryRangesFor}} (passed in as an argument) and the set of tokens used in calls by {{getPredecessor}} (the system ones) should be investigated.
