Hmm, that makes a certain sense.
But then I seem to be getting errors like
ERROR: Error CREATEing SolrCore 'nutch': Unable to create core [nutch]
Caused by: enablePositionIncrements is not a valid option as of Lucene 5.0
Like the Nutch schema is for a much older Solr ?
What version were you running ?

I had the same problem a while ago; I accidentally forgot to supply the schema
when creating a core and had the digest/string*s* problem. Here's some more
explanation of what I did, I hope I remember correctly:
I am using (just like Markus suggested) the schema.xml from nutch which sets
<fieldType name="string" class="solr.StrField" ...
and
<field name="digest" type="string" ...
I duplicated the data_driven_schema_configs/conf/ configset and replaced the
managed-schema file with Nutch's schema.xml so I have:
[...]/solr/configsets/my_config/managed_schema
Core is created like so:
solr create -c corename -d my_config
Hope that helps,
Felix

Betreff: RE: Nutch 2, Solr 5 - solrdedup causes ClassCastException:
Yes, current Solr comes with a schemaless mode, which can cause errors in
some cases. It must be configured to use classic schema mode, then you provide
it with the schema.xml file you can find in Nutch' conf directory.

I don't understand what you mean here. I am not a Solr expert, though
I've used it a bit in the past, though not with Nutch.
Is there a schema I should be feeding it ?

Solr supports schemaless mode, which may be your case. Perhaps it made
your digest field multi valued. I'd suggest to use Solr's classic schema
factory,
and a fixed schema.
