I think this started happening because test_webpages toggles the log level and
was enable recently IMPALA-7691. Clearly we shouldn't be hitting this DCHECK
anyway.
It looks like this is a FIXED_UDA_INTERMEDIATE, so I think the batches being
logged were being shuffled as part of the exchange for an aggregate:

I think this started happening because test_webpages toggles the log level and
was enable recently IMPALA-7691. Clearly we shouldn't be hitting this DCHECK
anyway.
I'll see if I can figure out what the type was based on the coredump.
