Mike Drob updated SOLR-7928:
----------------------------
Attachment: SOLR-7928.patch
Modified the patch to delete the directory between every test. I wasn't getting
the same failures as you were, Greg, but I suspect that this will take care of
them and is much faster than the alternative approach of starting up a new DFS
Cluster each time.
Added a couple more javadocs in addition to what you had. precommit is still
failing on {{build/docs/core/org/apache/lucene/index/CheckIndex.Options.html
missing Constructors: Options--}}, but I'm not sure how to cleanly address
that. There is no constructor defined, so the docs must be picking up the
default one, which we can't document since it doesn't exist...

> CheckIndex is very useful for testing an index for corruption. However, it
> can only work with an index on an FSDirectory, meaning that if you need to
> check an Hdfs Index, then you have to download it to local disk (which can be
> very large).
> We should have a way to natively check index on hdfs for corruption.
