Simon Willnauer updated LUCENE-3709:
------------------------------------
Attachment: LUCENE-3709.patch
this patch seems to fix the problem for me. The issue here is that we still try
to merge norms even if there are are no norms present. FIS only checks if its
indexed and does not omit norms. This means we actually try to merge it but
possibly don't write any norms cfs.
> norms reading fails with FileNotFound in exceptional case
