写入Doris数据时一直报Caused by: org.apache.http.ProtocolException: The server failed to respond with a valid HTTP response错误，但使用mysqlwriter可以成功写入

相同的配置下，mysqlwriter可以成功写入，但是Doris一直报错，Caused by: org.apache.http.ProtocolException: The server failed to respond with a valid HTTP response。不知道该如何排查，在网上查看相关相似解决方案，已经将pom中的httpclient更新为4.5.13版本，并将本地编译的doriswriter包替换了原本的包，仍然无法解决问题。

Start by reproducing the failure with the reported Doris writer configuration and trace the stream-load call from DorisWriterManager.java into DorisStreamLoadObserver.java, especially the reported lines 163, 170, and 183. Check the endpoint and HTTP response involved in the stream-load request; the issue is done when the cause is identified and the writer can successfully load data or reports a clear diagnostic.
