-----------------------------------------
Key: CASSANDRA-2847
URL: https://issues.apache.org/jira/browse/CASSANDRA-2847
Project: Cassandra
Issue Type: Bug
Components: Core
Affects Versions: 0.8.1
Reporter: Thibaut
Priority: Critical
Hi,
we upgraded our test cluster from 0.7.* to 0.8.1. We did run nodetool scrub on
each node, and then nodetool repair (Repair might not have finished so far). We
also upgradet to hector 0.8.1
We tried to run our application and get_range_slices fails with the following
error:
