Adrien Grand resolved LUCENE-8252.
----------------------------------
Resolution: Invalid
This error indicates that your shard is corrupt indeed. We automatically verify
checksums on merge since we need to read the data for the merge anyway, so it
only introduces little additional CPU overhead. However checking a read-only
index that is heavily searched is more challenging since you don't want the
checksum verifications to trash your I/O cache.

> Key: LUCENE-8252
> URL: https://issues.apache.org/jira/browse/LUCENE-8252
> Project: Lucene - Core
> Issue Type: Bug
> Affects Versions: 6.6.2
> Reporter: Michael Braun
> Priority: Major
>
> We hit this on an autowarming query with a phrase on a particular shard, and
> it keeps happening with similar errors (and on other position-sensitive
> queries) post-restart on both that particular autowarming query and other
> queries. I'm guessing somehow a file in the index got written incorrectly
> with regard to positions.
