unable to generate solr schema with cassandra datastax

Question

I'm using datastax enterprise 5.0.2 and I want to use solr

I try this :

dsetool create_core keyspace.table generateResources=true reindex=true

But I get this :

org.apache.solr.client.solrj.impl.HttpSolrServer$RemoteSolrException: Type org.apache.cassandra.db.marshal.ByteType is not supported with automatic Solr schema generation.
Specify 'lenient: true' in your resource generation options to ignore unsupported columns.

And when I try with lenient true I can't make it work either because my primary key has a byte field named 'type'

org.apache.solr.client.solrj.impl.HttpSolrServer$RemoteSolrException: Schema Parsing Failed: Schema contains no indexed field for element 'type' of composite key '(lang,type)

Any clue how to resolve this ?

My table has over 100 fields it will be hard to generate it manually

Do you get a response if you use infer_solr_schema ? docs.datastax.com/en/datastax_enterprise/5.0/… — markc
no, the byte type is not supported even when mapping manually and/or in lenient mode — Bouki
If you can generate duplicate dummy table without this byte type then create the schema from that then you could use this to for the original table. You might possibly be able to set stored=false and indexed=false and still have it in the schema — markc
Already tried that, but doesn't work either. I ended up using int, not the best solution but a working one — Bouki

Take out the

reindix=true.

On first creation just do it like this:

dsetool create_core keyspace.table generateResources=true

later on you can reindex
