Connection link failure can refer to 连接池与连接参数 | PingCAP 文档中心 and the Asktug posts. Additionally, you can also try reducing the batch size for Kettle imports.

“Negative Repeat Count” probably means “负重复次数”. Take a look at the logic of batch splitting in Kettle.

This error is generally due to too many connections, which makes it too busy to handle. Replace it with OOM (Out of Memory) in this case.
