We are experiencing massive writes to column families when only doing reads from Cassandra. A set of 5 hadoop jobs are reading from Cassandra and then writing out to hdfs. That is the only thing operating on the cluster. We are reading at CL.QUORUM with hadoop and have written with CL.QUORUM. Read repair chance is set to 0.0 on all column families. However, in the logs, I'm seeing flush after flush of memtables and compactions taking place. Is there something else that would be writing based on the above description?
