AFAIK Cassandra will just pick the directory with the most space.
Also AFAIK using multiple directories should only be considered a safety valve
to fix problems such as the one you describe see

Hi All,
I had a single directory designated as data file directory in
cassandra ,but it ran out of space .I am adding a new data directory in
addition to the one I have .What should I do so that cassandra balance the
space on both of them.
Thanks
Anurag
