cassandra-loader generates tombstones when the inserted rows have null values.
I know there were a couple of closed issues around this topic, but it doesn't look like it is fixed.
I was testing it with version 0.0.23 and cassandra 3.0
My bad, there is the -nullsUnset does the job.
It was not described in the "Option" section of the Readme. It is described in the "Usage Statement" section.
