Mike Drob created LUCENE-7662:
---------------------------------
Summary: Index with missing files should throw
CorruptIndexException
Key: LUCENE-7662
URL: https://issues.apache.org/jira/browse/LUCENE-7662
Project: Lucene - Core
Issue Type: Bug
Components: core/index
Affects Versions: 6.4
Reporter: Mike Drob
Similar to what we did in LUCENE-7592 for EOF, we should catch missing files
and rethrow those as CorruptIndexException.
If a particular codec can handle missing files, it should be proactive check
for those optional files and not throw anything, so I think we can safely do
this at SegmentReader or SegmentCoreReaders level.
