[jira] [Created] (LUCENE-7562) CompletionFieldsConsumer throws NPE on ghost fields

Michael McCandless created LUCENE-7562:
------------------------------------------

             Summary: CompletionFieldsConsumer throws NPE on ghost fields
                 Key: LUCENE-7562
                 URL: https://issues.apache.org/jira/browse/LUCENE-7562
             Project: Lucene - Core
          Issue Type: Bug
            Reporter: Michael McCandless
            Assignee: Michael McCandless
             Fix For: master (7.0), 6.4


If you index {{SuggestField}} for some field X, but later delete all documents with that field, it can cause a ghost situation where the field infos believes field X exists yet the postings do not.

I believe this bug is the root cause of this ES issue: https://github.com/elastic/elasticsearch/issues/21500
