Description
The issue title reflects Mark Miller's initial diagnosis of the problem.
Here are my symptoms:
This is regarding the backup feature of replication, as opposed to replication. Backups seem to work fine on toy indexes. When trying backups out on a copy of my production index (300GB-ish), though, I'm getting FileNotFoundExceptions. These cancel the backup, and delete the snapshot.yyyymmdd* directory. It seems reproducible, in that every time I try to make a backup of my large index it will fail the same way.
This is Solr r815830. I'm not sure if this is something that would potentially be addressed by SOLR-1458? (That patch is from after r815830.)
For now I'm not using any event-based backup triggers; instead I'm manually hitting
http://master_host:port/solr/replication?command=backup
This successfully sets off a snapshot, as seen in a thread dump. However, after a while the snapshot fails. I'll paste in a couple of stack traces below.
I haven't seen any other evidence that my index is corrupt; in particular, searching the index and Java-based replication seem to be working fine, and the Lucene CheckIndex tool did not report any problems with the index.
