使用的示例：
https://github.com/alibaba/DataX/blob/master/hologresjdbcwriter/doc/hologresjdbcwriter.md

Start with hologresjdbcwriter/doc/hologresjdbcwriter.md and reproduce the official example against Hologres using the reported configuration. Compare the resulting HoloClient 2.1.0 stack trace and set-returned-function error with the writer's SQL or schema handling. Done means identifying a reproducible cause and documenting or correcting the example so the synchronization succeeds.
