Re: Converting from Apache Cassandra 2.2.6 to 3.x

2018-02-01 Thread Christopher Lord 
If upgrading to 3.11.x be aware of the dropped support for the legacy auth
tables. The relevant notes from NEWS.txt:

The authentication & authorization subsystems have been redesigned to
 support role based access control (RBAC), resulting in a change to the
 schema of the system_auth keyspace. See below for more detail.
 For systems already using the internal auth implementations, the
process
 for converting existing data during a rolling upgrade is
straightforward.
 As each node is restarted, it will attempt to convert any data in the
 legacy tables into the new schema. Until enough nodes to satisfy the
 replication strategy for the system_auth keyspace are upgraded and so
have
 the new schema, this conversion will fail with the failure being
reported
 in the system log.
 During the upgrade, Cassandra's internal auth classes will continue to
use
 the legacy tables, so clients experience no disruption. Issuing DCL
 statements during an upgrade is not supported.
 Once all nodes are upgraded, an operator with superuser privileges
should
 drop the legacy tables, system_auth.users, system_auth.credentials and
 system_auth.permissions. Doing so will prompt Cassandra to switch over
to
 the new tables without requiring any further intervention.
 While the legacy tables are present a restarted node will re-run the
data
 conversion and report the outcome so that operators can verify that it
is
safe to drop them.


If you don't drop these legacy tables before the upgrade you may find
yourself unable to access the cluster.
