Mike Drob updated SOLR-7928:
----------------------------
Attachment: SOLR-7928.patch
Attached is one possible approach. This adds a new command line tool,
CheckHdfsIndex that builds the HdfsDirectory before passing it to the
CheckIndex internals. This approach avoids adding a dependency from lucene to
hdfs, leaving it only in solr, which may be more desirable than adding direct
support in CheckIndex.

> 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.
