OpsCenter 4.0 User Guide

Timeout connecting to Cassandra 2.0 clusters

OpsCenter will timeout when connecting to Cassandra 2.0 clusters when rpc_server_type=hsha in cassandra.yaml.

Due to a bug in Cassandra 2.0 (CASSANDRA-6373), the connection from opscenterd over thrift will hang, causing a timeout in OpsCenter. The workaround is to change the rpc_server_type setting to rpc_server_type=sync in cassandra.yaml.
