             Summary: Compound file writing should verify checksum of its sub-files
                 Key: LUCENE-7323
                 URL: https://issues.apache.org/jira/browse/LUCENE-7323
             Project: Lucene - Core
          Issue Type: Improvement
            Reporter: Michael McCandless
            Assignee: Michael McCandless
             Fix For: master (7.0), 6.2


For larger segments, there is a non-trivial window, from when IW
writes sub-files, to when it then builds the CFS, during which the
files can become corrupted (from external process, bad filesystem,
hardware, etc.)

Today we quietly build the CFS even if the sub-files are corrupted,
but we can easily detect it, letting users catch corruption earlier
(write time instead of read time).
