Re: Errors with Cassandra 1.0.10, 1.1.0, 1.1.1-SNAPSHOT and 1.2.0-SNAPSHOT

2012-06-13 Thread Horacio G. de Oro 
Hi! I've found that in all cases, the errors happened when running the
tests cases of the application. Before running each tests case, a test
keyspace is created, then the tests are executed, and the keyspace is
removed.

The repeated creation, use and removal of a keyspace causes that kind of
errors, but the tests ran ok... that errors are not propagated to the
application...

Thanks!
Horacio

Hi! While using Cassandra, I've seen this log messages when running some
test cases (which insert lots of columns in 4 rows).
I've tryied Cassandra 1.0.10, 1.1.0, 1.1.1-SNAPSHOT and 1.2.0-SNAPSHOT
(built from git). I'm using the default configuration, Oracle jdk 1.6.0_32,
Ubuntu 12.04 and pycassa.

Since I'm very new to Cassandra (I'm just starting to learn it) I don't
know if I'm doing something wrong, or maybe there are some bugs in the
several versions of Cassandra I've tested.
