Can combine segments from two datasources using the combining firehose?

Hi,

I want to combine segments from two datasources and load into a new datasource using the combining firehose, but the ingestion job never success (or “success” in 5 sec).

Does the combining firehose work for my case?

There is an open issue, are you running into something similar https://github.com/apache/druid/issues/9389

Yes, I got the same error.

btw, in 0.18 version, is there a solution with inputsource rather than firehose?
