使用Pelops在Cassandra中批量上传数据

我用Pelops和Cassandra一起工作。我想使用mutator插入批量数据。当我插入大约20000条记录时，它工作正常，但当我超过记录数时，它会显示“由对等方重置连接：套接字写入错误”。我正在编写以下代码

Pelops.addPool(CASSANDRA_POOL, new Cluster(CASSANDRA_HOST,
            CASSANDRA_PORT), CASSANDRA_KEYSPACE);
Mutator mutator = Pelops.createMutator(CASSANDRA_POOL);

//writing cols in mutator
mutator.execute(CL_ONE)

但它正在为一些数量有限的记录工作

我遇到以下错误：
