[SOLR-8291] NPE calling export handler when useFilterForSortedQuery=true

• Type: Bug
• Status: Open
• Priority: Major
• Resolution: Unresolved
• Affects Version/s: 5.2.1
• Component/s: SolrCloud
• Assignee: Unassigned

Description

Updated: The stacktrace below was created when the solrconfig.xml has the following element:

 <useFilterForSortedQuery>true</useFilterForSortedQuery>

It was determined that useFilterForSortedQuery is incompatible with the /export handler.

See the comments near the end of the ticket for a potential work around if this flag needs to be set.
