I've recently tried upgrading a small single node test cluster from DSE 2.1 to 2.2.1. However when I start Cassandra (dse cassandra -t) it soon is using 100% CPU and continuously logging this until I kill it:
WARN [TASK-TRACKER-INIT] 2012-11-07 15:07:46,589 MetricsSystemImpl.java (line 200) Source name ugi already exists!
Any idea how I can fix this?
