Anshum Gupta commented on SOLR-6640:
------------------------------------
Thanks for wrapping this one up Mark. Looks good!
I think it'd be good to declare a final int MIN_FILE_SIZE or something to use
in filesToAlwaysDownloadIfNoChecksums. Also, the comment says files < 100kb
would be copied but the check seems to be for 100,000 bytes or about 97kb? It's
ok but I think but we should either change the comment or the number (nothing
pressing).
Also, I think the concat of 2 strings while logging was an IDE issue
{code:title=SnapPuller.java}
LOG.warn(
"File {} did not match. " + "expected length is {} and actual
length is {}",
filename, backupIndexFileChecksum, indexFileChecksum,
{code}
> Replication can cause index corruption.
