Jason Gerlowski commented on SOLR-15378:
----------------------------------------
I've seen this before actually! In short: backup/restore doesn't support
SimpleTextCodec.
The restore code checks for a footer in all index files that it restores, to
make sure no corruption occurs while moving the files back and forth.
SimpleTextCodec, unlike almost all other Codecs, doesn't include this footer in
its files and so attempts to backup or restore a SimpleTextCodec index will
fail.
The "fix" for this should be to add a {{@SuppressCodec}} annotation to the
test, to ensure it's never used with SimpleTextCodec.
> Reproducible failure in TestRestoreCore in branch_8x
