Can't modify 'vm.swapiness' or 'vm.max_map_count' for Cassandra

2014-03-23 Thread user 01
While installing Datastax community Cassandra I got the error: *error: permission denied on key 'vm.max_map_count'* > Because I 'm running cassandra in an OpenVZ container my host does not allow changing *vm.swapiness* or *vm.max_map_count* due to shared kernel. Is it OK to ignore these errors ?

No output.log is ever generated by my cassandra installation(DSC20 with C* 2.0.6 on Ubuntu 12.04). Do I need to configure anything to enable logs to output.log ?
