Sam Tunnicliffe commented on CASSANDRA-11942:
---------------------------------------------
Roles were introduced in 2.2 and the default role manager requires that all
nodes in the cluster are running at least that version to be sure that the
underlying tables are available. The version a peer is running is learned when
messages are exchanged, so the role manager's setup includes a delay to allow
for some exchanges to take place. By default this is 10s and during that
period, any DCL statements, e.g. {{(CREATE|ALTER|GRANT|REVOKE) ROLE...)}}, will
be rejected in the way you described.
If you're in an environment where you're sure the whole cluster is on the right
version and adding a delay or retry in the client is not an option, during
automated testing for instance, you can reduce the delay period using the
system property {{cassandra.superuser_setup_delay_ms}}. Adding a value for that
in {{conf/jvm.options}} or on the command line when starting Cassandra will
override the default value.

> Project: Cassandra
> Issue Type: Bug
> Environment: Ubuntu 14.04.4
> Cassandra 3.0.6 (single node)
> Python (2.7) connector with Native protocol v3
> Reporter: Petr Malik
>
> I get the following error from Python client when executing ALTER USER 'foo'
> WITH PASSWORD %s; just after service restart.
> It works if I wait for some 5s before executing the statement.
> From system.log:
> 2016-06-01 22:07:01.458 InvalidRequest: Error from server: code=2200 [Invalid
> query] message="Cannot process role related query as the role manager isn't
> yet setup. This is
> likely because some of nodes in the cluster are on version 2.1 or earlier.
> You need to upgrade all nodes to Cassandra 2.2 or more to use roles."
