Ivo Ladage - van Doorn commented on AMDATUCASSANDRA-36:
-------------------------------------------------------
Added a Unit test that could reproduce the issue mentioned in
AMDATUCASSANDRA-65.
In fact I added two unit tests; one using the deprecated Thrift PM and one
using the new Hector PM.
Now the issue can still be reproduced using the Thrift PM, but cannot be
reproduced using the Hector PM.
So apparently, we did something wrong in our implementation of the Thrift based
PM. Note that we did find more related issues in the Thrift based PM, like
tombstone records still being returned as real rows (see AMDATUCASSANDRA-15).
So the final conclusion on this issue is: the problem was caused by an
incorrect implementation of our Thrift-based PM. Switching to the Hector API
resolved the problem. Case closed.
I will commit the unit tests, but disable the Thrift PM one (as that will fail).
