創建表時，Cassandra system_schema鍵空間不可用戶修改

[英]Cassandra system_schema keyspace is not user-modifiable when creating table

 原文  2016-11-27 07:09:08  6   1    java/ cassandra/ datastax

問題描述

我有一個Java應用程序，它通過執行查詢來一次初始化應用程序中使用的所有cassandra表。 它在本地運行良好，並與帶有Apache Cassandra 3.3的遠程測試服務器一起運行。 但是，當我在具有3個節點的Cassandra 3.3集群的生產環境中運行它時，它將創建前22個表，並始終在一個特定的表處停止，並顯示錯誤 

ERROR UNAUTHORIZED: system_schema keyspace is not user-modifiable.

導致此問題的查詢是：

如果不存在則創建表userrecom_newusers（userid bigint，timestamp bigint，PRIMARY KEY（userid））

並且它使用鍵空間“ prosolo_logs_moocs”，因此它與system_schema沒有任何關系。

創建這些表的Java代碼是： 

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();
            }
        }

從Datastax DevCenter可以很好地執行此查詢。 我正在使用datastax cassandra驅動程序3.0.0。

知道可能是什么問題嗎？

更新：

這是我用來連接集群的代碼： 

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);
}

經過幾次更改后，我現在遇到了異常 

Caused by: com.datastax.driver.core.exceptions.InvalidQueryException: unconfigured table logevents

更新2：

看來我遇到的所有問題都與配置不正確的群集有關。 即使nodetool狀態指示所有節點都已連接，但某些節點還是無法訪問的，並且存在架構分歧。 解決這些問題后，一切都很好。

這是Java中的工作代碼： 

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)");
    }
}
