Varun Thacker commented on SOLR-6920:
-------------------------------------
When using a try-finally block code in SOLR-6440 the threads don't hang
anymore.
The test still fails because of errors like this -

No .liv files get included with the logic change in
ReplicationHandler.getFileList with the patch. Looking into that now.
> During replication use checksums to verify if files are the same

> Key: SOLR-6920
> URL: https://issues.apache.org/jira/browse/SOLR-6920
> Project: Solr
> Issue Type: Bug
> Components: replication (java)
> Reporter: Varun Thacker
> Attachments: SOLR-6920.patch
>
>
> Currently we check if an index file on the master and slave is the same by
> checking if it's name and file length match.
> With LUCENE-2446 we now have a checksums for each index file in the segment.
> We should leverage this to verify if two files are the same.
> Places like SnapPuller.isIndexStale and SnapPuller.downloadIndexFiles should
> check against the checksum also.
