--------------------------------
Summary: "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: Core
Reporter: tzach
Priority: Minor
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.
