Currently we update the effective_replication_map only on non-system keyspace, leaving the system keyspace, that uses the local replication strategy, with the empty replication_map, as it was first initialized. This may lead to a crash when get_ranges is called later as seen in #9494 where get_ranges was called from the perform_sstable_upgrade path. This change updates the effective_replication_map on all keyspaces rather than just on the non-system ones and adds a unit test that reproduces #9494 without the fix and passes with it. Fixes #9494 Test: unit(dev), database_test(debug) Signed-off-by: Benny Halevy <bhalevy@scylladb.com> Message-Id: <20211020143217.243949-1-bhalevy@scylladb.com>
