[jira] [Reopened] (CASSANDRA-10209) Missing role manager in cassandra.yaml causes unexpected behaviour

["Michael Shuler (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/CASSANDRA-10209?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Michael Shuler reopened CASSANDRA-10209:
----------------------------------------

This patch causes an NPE in CQLSSTableWriterClientTest. CI showed this commit as the regression, and I can repro - previous commit passes this test OK.

> On upgrading to 2.2+, if the new {{role_manager}} option is not added to {{cassandra.yaml}}, an instance of the default {{CassandraRoleManager}} is created during initialization of {{DatabaseDescriptor}}. This is a problem as the set of role options supported by {{CRM}} depends on the configured {{IAuthenticator}}, which at that point in time is always {{AllowAllAuthenticator}}.
> This StackOverflow post describes the problem; the configured authenticator is {{PasswordAuthenticator}}, the role manager should allow roles to be created using the {{PASSWORD}} option, but it does not.
> http://stackoverflow.com/questions/31820914/in-cassandra-2-2-unable-to-create-role-containing-password
> The simple workaround is to ensure that yaml contains the role manager option
> {code}
> role_manager: CassandraRoleManager
> {code}
