----------------------------------
Environment:
This bug is in Hector code.
If there is exception in addCassandraHost() before adding host to hostPools,
since addCassandraHost does not throw exception, the host will be removed from
downedHostQueue, and the host will be gone forever.
if(downedHostQueue.contains(cassandraHost) &&
verifyConnection(cassandraHost)) {
connectionManager.addCassandraHost(cassandraHost);
downedHostQueue.remove(cassandraHost);
return;
}
