first, do not be scared of this error that although this is a Excepiton, but its tip is WARN level, after the bloggers actually use proven, does not affect the normal use of cassandra.
Presumably node configuration and repetition factor caused unreasonable. Since it does not affect the use, you can ignore. End.
