------------------------------------------------------------

Is the problem link to adding data to a cluster with less nodes than RF?
Because in my second test, I could add new nodes despite having only 2 nodes when I added
the data.
And I had the crash after calling "nodetool loadbalance", I had 4 active nodes.

      was (Author: nahor):
    What's the problem exactly? In my second test, I had 4 nodes when I called "nodetool loadbalance"
(but not when I added the data). Is the problem specifically when adding data to a cluster
with less nodes than RF?
