Joel Bernstein commented on SOLR-8295: -------------------------------------- Ah, this is already fixed. I was looking into a bug report today on the users list for 5.3.1. This bug was introduced in the 5x branch when the numeric docValues support was added. I suspect it took a long time to surface because many people are still using the 4x line of code. In the 4x line of code everything was based on a top level field cache which couldn't have this problem. I'll report back to the users list about this. > collapse parser can trigger NPE when a segment has empty DocValues for > collapse field (ie: no doc in segment has a value) > ------------------------------------------------------------------------------------------------------------------------- > > Key: SOLR-8295 > URL: https://issues.apache.org/jira/browse/SOLR-8295 > Project: Solr > Issue Type: Bug > Reporter: Steve Rowe > Assignee: Hoss Man > Fix For: 5.4, Trunk > > Attachments: SOLR-8295.patch > > > When collapsing on a field that doesn't exist for all documents, the > existence of a segment that does not contain any documents that have a value > can cause an NPE as the collapse parser assumes the DocValues for a segment > will always be non-null. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
