If it stays like this for a while, it sounds like your bootstraps have
hung. Note that in general you should add nodes one at a time, especially
if you are in a version without the fix for CASSANDRA-2434, in theory
adding multiple nodes "at once" might contribute to their bootstraps
hanging.

Stop cassandra on the joining nodes, wipe/move aside their data
directories, and try again one at a time.
