Erick Tryzelaar commented on CASSANDRA-1012:
--------------------------------------------
So here's what I'm seeing in my log files with my inserts and gets. And by
saying "inserting into machine1", I mean that my client is connecting to
machine1, but machine1, machine2, and machine3 are all in a ring together and
appear to have normal communication with each other:

> Problems reading remote rows in trunk?
> --------------------------------------
>
> Key: CASSANDRA-1012
> URL: https://issues.apache.org/jira/browse/CASSANDRA-1012
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Affects Versions: 0.7
> Reporter: Erick Tryzelaar
>
> I've run into a problem with my small 3 node cluster where quorum reads do
> not return anything. I'm inserting 10 rows into a fresh database with
> replication factor 3. I've inserted with QUORUM, but when I try to read back
> at QUORUM no data gets returned. However, if I use the consistency level ONE,
> I do get results.
> I've dug a bit into this problem, and it appears that internally
> ThriftServer.getSlice is finding the column family for the given key, but
> it's not finding any of the columns, so thrift doesn't return anything.
> In order to confirm there being a problem, I dropped the RF down to 1 and
> rebuilt the cluster. I then reinserted some data, and I can only read data
> off of one machine.
