Sylvain Lebresne commented on CASSANDRA-2773:
---------------------------------------------
Actually, there isn't really much risk for data loss given that as Jonathan
said, if you hit that, it's fairly easy to go back to 0.7.5, fix client code
and upgrade again. Granted this is not user friendly and not something you
should expect from a minor upgrade, but let at least set the record straight on
the data loss part.
That being said, I don't think the patch on this ticket could screw up indexes
more that we use to prior to 0.7.6, so maybe we can commit to 0.7.7 on that
ground.
I'd still suggest fixing client code in the meantime.

> Project: Cassandra
> Issue Type: Bug
> Affects Versions: 0.7.0
> Reporter: Boris Yen
> Assignee: Jonathan Ellis
> Priority: Critical
> Fix For: 0.8.2

> 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.
