Chef somehow ran in that box and updated the schema with a version of it
that had RF=1.
Sorry about that.

Hey folks, perhaps a dumb question but I ran into this situation and it's a
bit unclear what's going on.
We are running a 3 nodes cluster with RF 3 (cass 1.0.11). We had one issue
with one node and it was down for like 1 hour.
I brought the node up again as soon as I realized it was down (and
Hi, Hector does not retry on a down server. In the unit tests where you have
just one server, Hector will pass the exception to the client.
Can you tell us please what your test looks like ?

SetRowCount is doing indexClause.setCount(rowCount);

And as Ed said, if you can provide the stacktrace that would help too.

Hi folks, I'm modeling the partitioned counters into Hector and given the

Is it possible do achieve? or are both in fact different mutations?

The recommendation is to wait few milliseconds and retry.
For Example if you use Hector ( I don't think it is your case), Hector will
retry to different nodes in your cluster and the retry mechanisms is tunable
as well.

Roshan, when a client invoke a write, the write goes first to commit log and

After it reaches the memtable, that data is ready to be read.

In Hector framework, take a look at TimeUUIDUtils.java
You can create a UUID using TimeUUIDUtils.getTimeUUID(long time);
or
TimeUUIDUtils.getTimeUUID
support Hector should expose.
Thoughts?

Hi, regarding the retrying strategy, I understand that it might make
sense assuming that the client can actually perform a retry.
We are trying to build a fault tolerance solution based on Cassandra.
In some scenarios, the client machine can go down during a
transaction.
Would it be bad design
for it so much.
