seatunnel同步oracle到clickhouse问题

拷贝oracle的包ojdbc6-11.2.0.4.jar到/opt/spark-2.3.3/jar目录下

## How to solve the Error `Exception in thread "main" java.lang.NoSuchFieldError: INSTANCE`?

The reason is that the version of httpclient.jar that comes with the CDH version of Spark is lower, and The httpclient version where ClickHouse JDBC is based on is 4.5.2, and the package version conflicts. The solution is to replace the jar package that comes with CDH with httpclient-4.5.2 version.

下载
httpclient-4.5.2 拷贝到
