Description

This test fails on 2.1, 2.2, and 3.0 versions tested on CassCI:

http://cassci.datastax.com/view/cassandra-2.1/job/cassandra-2.1_dtest/lastCompletedBuild/testReport/bootstrap_test/TestBootstrap/simultaneous_bootstrap_test/
http://cassci.datastax.com/view/cassandra-2.2/job/cassandra-2.2_dtest/350/testReport/junit/bootstrap_test/TestBootstrap/simultaneous_bootstrap_test/
http://cassci.datastax.com/view/cassandra-3.0/job/cassandra-3.0_dtest/lastCompletedBuild/testReport/bootstrap_test/TestBootstrap/simultaneous_bootstrap_test/

It fails with the same error, indicating that the third node, which should not start while another node is bootstrapping, started. Oddly, the assertion just before it, looking for a particular error in the logs, succeeds.

This could be a race condition, where one node successfully completes bootstrapping before the third node is started. However, I don't know how likely that is, since it fails consistently. Unfortunately, we don't have enough history on CassCI to show when the test failure started.

I'm assigning yukim for now, feel free to reassign.
