What happened

When use clickhouse-jdbc query clickhouse data with skywalking-java 9.4.0 by http 8123 port occur error clickhouse unknownException 1002

Clickhouse-server occur 400 bad request exception.

What you expected to happen

Normal query.

How to reproduce

Query clickhouse with skywalking-java agent by http .

Anything else

The problem is because skywalking-java agent will set few header in http request.
But clickhouse may check those header hardly then throw 400 error.
I set the environment config : SW_EXCLUDE_PLUGINS=httpclient-4.x then this problem fixed.
So will you check and fix this bug?

This looks like a collaborative x-plugin code interaction. httpclient plugin needs to follow some flag in running time context, and decide whether to inject header or not.

[Echo-C-Yi]

Yes，but i think it may consider whether target server will reject those header or not.
Right now, this situation has occur , would you fixed this conflict in http client plugin and clickhouse server?
