Unknown CF 83951d71-78c9-1ec6-e1ec-7d0034f511f1

使用 cassandrawriter 写入数据到阿里云的lindorm时，如果在job JSON文件中设置 batchSize > 1的值，比如 batchSize: 2 就会抛出这个 Unknown CF的错误

batchSize=1时，用的是com.datastax.driver.core.BoundStatement，这个没问题
batchSize > 1时，用的是 com.datastax.driver.core.BatchStatemet，lindorm好像对这个不太兼容

Start at the cassandrawriter entry point and inspect how the job JSON's batchSize selects BoundStatement versus BatchStatement. Reproduce with batchSize=2 against Lindorm and compare the resulting Unknown CF behavior; done requires a confirmed compatible outcome or a narrowly documented limitation.
