我有java应用程序通过执行查询初始化应用程序中使用的所有cassandra表。它在本地运行良好，并与Apache Cassandra 3.3的远程测试服务器。但是，当我在具有3个节点的Cassandra 3.3集群的生产中运行它时，它会创建前22个表并始终在一个特定的表上停止并显示错误
ERROR UNAUTHORIZED: system_schema keyspace is not user-modifiable.
产生此问题的查询是：
CREATE TABLE IF NOT NOT EXISTS userrecom_newusers（userid bigint，timestamp bigint，PRIMARY KEY（userid））
它使用密钥空间“prosolo_logs_moocs”，因此它与system_schema没有任何关系。
创建这些表的Java代码是：
this.createSchemaIfNotExists(this.getSession(), this.dbName,
this.dbConfig.replicationFactor);
Metadata metadata = this.getCluster().getMetadata();
metadata.getKeyspace(keyspacename).getTables();
this.getSession().execute("USE "+keyspacename);
for (String ddl : this.ddls) {
try {
this.getSession().execute(ddl);
} catch (Exception ex) {
logger.error("Error during the creation of table:"
+ keyspacename + " for DDL:" + ddl);
ex.printStackTrace();
}
}

此查询从Datastax DevCenter执行得很好。我正在使用datastax cassandra驱动程序3.0.0。
知道可能是什么问题吗？
更新：
这是我用来连接群集的代码：
public void connect(String node, int dbPort, String keyspace, int replicationFactor) {
System.out.println("CONNECTING CASSANDRA:"+node+" keyspace:"+keyspace);
if (this.session != null) {
return;
}
if (this.cluster != null) {
return;
}
/*cluster = Cluster.builder().addContactPoint(node).build();*/
this.cluster = Cluster.builder()
.withPoolingOptions( getPoolingOptions())
.withRetryPolicy(DowngradingConsistencyRetryPolicy.INSTANCE)
.withReconnectionPolicy(new ConstantReconnectionPolicy(100L))
.withPort(dbPort)
.addContactPoint(node).build();
Metadata metadata = cluster.getMetadata();
System.out.printf("Connected to cluster: %s\n",
metadata.getClusterName());
for ( Host host : metadata.getAllHosts() ) {
System.out.printf("Datacenter: %s; Host: %s; Rack: %s\n",
host.getDatacenter(), host.getAddress(), host.getRack());
}
if (keyspace != null) {
try {
this.session = this.cluster.connect(keyspace);
} catch (InvalidQueryException iqu) {
logger.error(iqu);
this.session = this.cluster.connect();
this.createSchemaIfNotExists(this.session, keyspace,
replicationFactor);
}
} else {
this.session = this.cluster.connect();
}
this.session.execute("USE "+keyspace);
}
在我做了几次更改之后，我现在得到了一个例外
Caused by: com.datastax.driver.core.exceptions.InvalidQueryException: unconfigured table logevents

更新2：
似乎我遇到的所有问题都与未正确配置的群集有关。即使nodetool状态指示所有节点都已连接，但某些节点无法访问，并且存在架构不一致。在我解决了这些问题之后，一切都很好。

以下是Java中的工作代码：
public static void main(String[] args) {
try (Cluster cluster = Cluster.builder().addContactPoints("127.0.0.1").withCredentials("username", "password").build(); Session session = cluster.connect("test")) {
createTableIfNotExist(cluster, session, "test");
}
}
private static void createTableIfNotExist(Cluster cluster, Session session, String keyspace) {
Metadata metadata = cluster.getMetadata();
TableMetadata tableMetadata = metadata.getKeyspace(keyspace).getTable("exp");
if (tableMetadata == null) {
session.execute("USE " + keyspace);
session.execute("CREATE TABLE exp(a int primary key, b int)");
}
}
