Steve Rowe created SOLR-5709:
--------------------------------
Summary: Highlighting grouped duplicate docs from different shards
with group.limit > 1 throws ArrayIndexOutOfBoundsException
Key: SOLR-5709
URL: https://issues.apache.org/jira/browse/SOLR-5709
Project: Solr
Issue Type: Bug
Components: highlighter
Affects Versions: 4.6, 4.5, 4.4, 4.3, 5.0
Reporter: Steve Rowe
Assignee: Steve Rowe
In a sharded (non-SolrCloud) deployment, if you index a document with the same
unique key value into more than one shard, and then try to highlight grouped
docs with more than one doc per group, where the grouped docs contain at least
one duplicate doc pair, you get an AIOOB.
Here's the stack trace I got from such a situation, with 1 doc indexed into
each shard in a 2-shard index, with {{group.limit=2}}:
