----------------------------------
Just tried, and failed to reproduce the issue so I cant give an accurate
answer.
As far as I remember the issue was not limited to the first few minutes.
> "Unknown keyspace system_traces" exception when using nodetool on a new
> cluster
> -------------------------------------------------------------------------------

> Key: CASSANDRA-9628
> URL: https://issues.apache.org/jira/browse/CASSANDRA-9628
> Project: Cassandra
> Issue Type: Bug
> Components: Tools
> Reporter: tzach
> Assignee: Carl Yeksigian
> Priority: Minor
> Fix For: 2.1.x
>
>
> When creating a new cluster from scratch, nodetool status fails on
> system_traces as follow
> {code}
> $ 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)
> ...
> {code}
> the problem disappear when creating an empty keyspace
> {code}
> cqlsh> create keyspace temp WITH REPLICATION = { 'class' : 'SimpleStrategy',
> 'replication_factor' : 2 };
> {code}
> 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.
