Version

flink-doris-connector-1.20-24.0.0

What's Wrong?

When I just specify fenodes I get

Failed to get response from Doris  http://some-fe:8030/api/FLINKUSER/TABLE1/_schema, http code is 303

In case I specify some-fe:8050 (the https port), I obviously get:

Failed to connect to host:http://some-fe:8050 java.net.SocketException: Unexpected end of file from server

If I try set fenodes to https://some-fe:8050:

Failed to connect to host:http://https://some-fe:8050 java.net.UnknownHostException: https

There are several places in code, where plain http is hardcoded, e.g.:

doris-flink-connector/flink-doris-connector/src/main/java/org/apache/doris/flink/rest/RestService.java

Line 362 in c61342f

String beUrl = "http://" + feNode + BACKENDS_V2;

What You Expected?

Support for https FE, either via explicit protocol specification via https://some-fe:port or by following redirect issued by FE.

How to Reproduce?

No response

Anything Else?

The format of fenodes is ip:port. https needs to configure the fe certificate https://doris.apache.org/zh-CN/docs/dev/admin-manual/auth/fe-certificate/. Currently, be does not support https

@JNSimba thank you. I opened merge request #494 to enable https connection to fe.
