Description

When creating a new cluster from scratch, nodetool status fails on system_traces as follow

$ nodetool status

error: Unknown keyspace system_traces
-- StackTrace --
java.lang.AssertionError: Unknown keyspace system_traces
	at org.apache.cassandra.db.Keyspace.<init>(Keyspace.java:270)
	at org.apache.cassandra.db.Keyspace.open(Keyspace.java:119)
	at org.apache.cassandra.db.Keyspace.open(Keyspace.java:96)
...

the problem disappear when creating an empty keyspace

cqlsh> create keyspace temp WITH REPLICATION = { 'class' : 'SimpleStrategy', 'replication_factor' : 2 };

My guess is system_traces initialization complete only after any data insertion.
Before it does, any attempt to read from it either from nodetool, cqlsh or streaming to a new node will fail.
