CombiningFirehose fails with java.lang.NullPointerException

Hi,

As part of PoC process I am making an attempt to combine a few test Druid data sources into one.

Can’t understand what I am doing wrong?

Druid 0.12.1 as part of HDP-3.0.0.0-1634 infrastructure

I have a PR open to solve problems like this: https://github.com/apache/incubator-druid/pull/7063

Though I thought this already worked for the local index task you’re using. Maybe that was a bug fix in 0.13?

Yep, bug fix in 0.13. Upgrade! :slight_smile:

Thank so much for clarification. :slight_smile:
