----------------------------------
Summary: Distributed grouping seems to require docValues in 5.x,
didn't in 4.x
Key: SOLR-8088
URL: https://issues.apache.org/jira/browse/SOLR-8088
Project: Solr
Issue Type: Bug
Affects Versions: 5.2.1
Reporter: Shawn Heisey
I have a field in my index that is lowercased after the KeywordTokenizer. I
wish to do grouping on this field. It is a distributed index.
This works fine in Solr 4.9.1 running on Java 8.
When I try the distributed grouping request (with the same schema) on Solr
5.2.1, it fails, with this exception:
{code}
java.lang.IllegalStateException: unexpected docvalues type SORTED_SET for field
'ip' (expected=SORTED). Use UninvertingReader or index with docvalues.
{code}
If I make the same request directly to one of the shards on 5.2.1, it works.
If I create a copyField to a field using StrField with docValues, the
distributed request works ... but then I lose the lowercasing.
