Subject Cassandra stuck at DataSink running on cluster
Date Fri, 26 Jun 2015 12:21:54 GMT


I am trying to write into Cassandra via the CqlBulkOutputFormat from an
apache flink program. 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,
