在安装 TiDB v6.0的时候,使用 Tiup 扩容的方式安装TiSpark集群,最高的版本是 TiSpark v2.4.1,没有最新的 Release TiSpark v2.5.1 。另外,TiSpark v2.5.0 及以上版本实现了部分鉴权与授权功能。
本次主要是体验
TiSpark v2.4.1 升级到 TiSpark v2.5.1
体验 TiSpark v2.5.1 的鉴权和授权功能
安装openjdk8 (略)
扩容的方式安装 TiSpark
tiup cluster scale-out cluster111 ./cluster111-v6.0.0-tispark.yml -uroot -p 2.3 测试 Spark v2.4.3 Standalonespark-defaults.conf 中增加配置
# sql扩展类 spark.sql.extensions org.apache.spark.sql.TiExtensions # master节点 spark.master spark://10.0.2.15:7077 # pd节点 多个pd用逗号隔开 如:10.16.20.1:2379,10.16.20.2:2379,10.16.20.3:2379 spark.tispark.pd.addresses 10.0.2.15:2379启动 Spark 集群

/tidb-deploy/tispark-master-7077/sbin/start-all.sh
启动Spark-shell
# 启动 spark-shell /tidb-deploy/tispark-master-7077/bin/spark-s启动 Spark-sql
# 启动 Spark-sql /tidb-deploy/tispark-master-7077/bin/spark-sql # 执行 select ti_version();参考:https://github.com/pingcap/tispark/blob/master/docs/authorization_userguide.md
Authorization and authentication through TiDB server
The databases user account must have the PROCESS privilege.
TiSpark version >= 2.5.0
Spark version = 3.0.x or 3.1.x
4.1 增加配置 spark-defaults.confspark.sql.tidb.addr 10.0.2.15 rue # in seconds. Values range from 5 to 3600 spark.sql.tidb.auth.refreshInterval 304.2 配置错误密码#这里是错误的密码 spark.sql.tidb.password abc启动 spark-sql 后使用 执行 sql 语句将报错
4.3 修正密码# 空密码 spark.sql.t启动 spark-sql
/tidb-deploy/tispark-master-7077/bin/spark-sqluse tidb_catalog; show databases; select CUSTOMER tablename , count(*) ct from tidb_catalog.TPCH_001.CUSTOMER union all select NATION tablename , count(*) ct from tidb_catalog.TPCH_001.NATION union all select REGION tablename , count(*) ct from tidb_catalog.TPCH_001.REGION union all select PART tablename , count(*) ct from tidb_catalog.TPCH_001.PART union all select SUPPLIER tablename , count(*) ct from tidb_catalog.TPCH_001.SUPPLIER union all select PARTSUPP tablename , count(*) ct from tidb_catalog.TPCH_001.PARTSUPP union all select ORDERS tablename , count(*) ct from tidb_catalog.TPCH_001.ORDERS union all select LINEITEM tablename , count(*) ct from tidb_catalog.TPCH_001.LINEITEM order by ct desc; 4.4 SparkSession 中配置密码spark.sqlContext.setConf("spark.sql.tidb.addr", your_tidb_server_address) spark.sqlContext.setConf("spark.sql.tidb.port", your_tidb_server_port) spark.sqlContext.setConf("spark.sql.tidb.user", your_tidb_server_user) spark.sqlContext.setConf("spark.sql.tidb.password", your_tidb_server_password)4.5 限制不能与 TiDB 以外的其他数据源一起工作
不支持基于角色的权限
TiDB Data Source API 不支持,例如 TiBatchWrite
本篇实践了 tiup list tispark --all 没有 TiSpark v2.5.x的情况下,升级到 TiSpark v2.5.1;
同时试用了 TiSpark v2.5.x 新支持的鉴权特性。
谢谢!
