Richard Low created CASSANDRA-6685:
--------------------------------------

             Summary: Nodes never bootstrap if schema is empty
                 Key: CASSANDRA-6685
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-6685
             Project: Cassandra
          Issue Type: Bug
          Components: Core
            Reporter: Richard Low


Since 1.2.15, bootstrap never completes if the schema is empty. The bootstrapping node endlessly prints:

 INFO 12:37:44,863 JOINING: waiting for schema information to complete

until you add something to the schema (i.e. create a keyspace).

The problem looks to be caused by CASSANDRA-6648, where MigrationManager.isReadForBootstrap() was changed to:

{{return Schema.instance.getVersion() != null && !Schema.emptyVersion.equals(Schema.instance.getVersion());}}

This is wrong since {{Schema.emptyVersion.equals(Schema.instance.getVersion())}} is always true if there is no schema.

We need some different logic for determining when the schema is propagated.

I haven't tested, but I expect this issue appears in 2.0.5 too.
