我无法执行应该更新 SimpleStrategy 键空间的复制因子的 cql 语句。这很烦人，因为这适用于所有三个版本的 CQLSH。

我正在使用的键空间上下文设置为使用 cqlv3 .setCqlVersion("3.0.0")

cql：

"ALTER KEYSPACE \"" + ksContext.getKeyspaceName() + "\" WITH REPLICATION = { " + 
            "'class' : 'SimpleStrategy', 'replication_factor' : 3 };";

堆栈跟踪：

InvalidRequestException(why:line 1:108 no viable alternative at character '}')

Astyanax 在 cql3 方面确实存在一些问题，但它取得了很大进展。创建一个新的键空间并使用 CQLv2（通过在上下文中设置它）并尝试不带"引号：

String query = "ALTER KEYSPACE " + keyspaceName + " WITH REPLICATION = { 
               'class' : 'SimpleStrategy', 'replication_factor' : 2 };";

注意*在此查询中，您将 rep 因子更新为2。
