Hi,
I am using Java 7. The cassandra version I use is actually 2.1.5, not 1.5. Sorry for the confusion. I also tried cassandra 2.1.6, but the problem stays the same.

Have you tested this with more recent versions of Cassandra? These new version have a lot of improvements related to SSTable reading and writing, and much more. I recommend you that you should use at least a 2.1.x version.

The program succeeds to write into a cassandra-cluster while the program is running locally on my pc. However, when trying to run the program on the cluster, it seems to get stuck at SSTableSimpleUnsortedWriter.put() waiting for the Diskwriter-Thread, that is not running anymore. I am using cassandra version 1.5 and apache flink version 0.9.0. Attached is the full stacktrace. Thanks in advance, Susanne
