Jonathan Ellis commented on CASSANDRA-2773:
-------------------------------------------

Thanks for the test case, Jim.

If by the same scenario, you mean the workload that left your commitlog throwing exceptions,
then yes please.

> I use hector 0.8.0-1 and cassandra 0.8.
> 1. create mutator by using hector api, 
> 2. Insert a few columns into the mutator for key "key1", cf "standard". 
> 3. add a deletion to the mutator to delete the record of "key1", cf "standard".
> 4. repeat 2 and 3
> 5. execute the mutator.
> the result: the connection seems to be held by the sever forever, it never returns. when
I tried to restart the cassandra I saw unsupportedexception : "Index manager cannot support
deleting and inserting into a row in the same mutation". and the cassandra is dead forever,
unless I delete the commitlog. 
> I would expect to get an exception when I execute the mutator, not after I restart the
cassandra.
