Version

3.1.4

What's Wrong?

We encountered an stream load error for wide tables after upgrading our cluster to version 3.1.4:

org.apache.doris.spark.exception.StreamLoadException: stream load failed, status: 431, reason: Request Header Fields Too Large

Even though changing FE config jetty_server_max_http_header_size to an extremely large number (such as 1048576 for 1MB header), the problem still exists.

We found that the properties for configuring jetty server in org.apache.doris.httpv2.HttpServer are out-dated after spring boot 2.3 been released.
