Hello,
When adding a new node to the cluster I need to wait for each node to receive
all the data from other nodes in the cluster or just wait a few minutes before
I start each node?

I have added new nodes to the existing cluster. In Opscenter I do not see any
streams... I presume that the new nodes get the data from the rest of the
cluster via streams. The existing cluster has TB magnitude, and space used in
the new nodes is ~90 GB. I must admit that I have restarted the new nodes
several times after adding them . Does this affect boostrap? AFAIK the new
nodes should start loading a part of all the data in the existing cluster.
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.
