Erick Erickson created SOLR-9802:
------------------------------------
Summary: Cannot group by a datefield in SolrCloud
Key: SOLR-9802
URL: https://issues.apache.org/jira/browse/SOLR-9802
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Reporter: Erick Erickson
While working on SOLR-5260 I ran across this. It is easily reproducible by
indexing techproducts to a two-shard collection and then
&group=true&group.field=manufacturedate_dt
This works fine stand-alone.
When 5260 gets checked in look in DocValuesNotIndexedTest.java for a reference
to this JIRA and take out the special processing that avoids this bug for a
unit test.
