为提高效率，请提供以下信息，问题描述清晰能够更快得到解决：
【 TiDB 使用环境】
自己搭建的集群。 3个tidb，3个pd，3个tispark，3个tikv分别在三个机器上。
【概述】 场景 + 问题概述
在spark中，写入数据库出错
【背景】 做过哪些操作
按照文档（https://docs.pingcap.com/zh/tidb/stable/get-started-with-tispark）导入 tispark-sample-data到tidb数据库。然后读出数据后，创建数据表，然后将将读出的数据写入后，出错：
”WARN RowIDAllocator: error during allocating row id“
其中，数据库表创建的脚本：
CREATE TABLE target_customer (
C_CUSTKEY int(11) NOT NULL,
C_NAME varchar(25) NOT NULL,
C_ADDRESS varchar(40) NOT NULL,
C_NATIONKEY int(11) NOT NULL,
C_PHONE char(15) NOT NULL,
C_ACCTBAL decimal(15,2) NOT NULL,
C_MKTSEGMENT char(10) NOT NULL,
C_COMMENT varchar(117) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_bin;
写入数据库的java代码是：
SparkConf conf = new SparkConf()
.setMaster(“local[*]”)
.setAppName(“TiSparkJavaExample”)
.set(“spark.sql.extensions”, “org.apache.spark.sql.TiExtensions”)
.set(“spark.tispark.pd.addresses”, “127.0.0.1:2379”);
SparkSession spark = SparkSession
.builder()
.config(conf)
.getOrCreate();
Dataset<Row> customers = spark.sql("select * from customer");
customers.write().format("tidb")
.option("tidb.addr", "127.0.0.1")
.option("tidb.port", "4000")
.option("tidb.user", "root")
.option("tidb.password", "")
.option("database", "tpch_001")
.option("table", "target_customer")
.mode("append")
.save();
spark.stop();
