-------------------------------------------------------------------------
The problem can easily be reproduced by directly invoking the Thrift API with
setValue and getValue.
I added a simple integration test:
- Loops over i=0 till 1000
- Invokes Iface.insert to set the value of a test column to i with
ConsistencyLevel set to ALL
- Invokes Iface.get to retrieve the value of the test column with
ConsistencyLevel set to ALL and compares if the value written equals the
retrieved value
This test always fails, but the value of i for which it fails is always 10! So
it seems that there is something special about the 10th value written to
Cassandra.
