HDFS replication factor

Hi,

when I configure my HDFS setup to use a specific replication factor, 
like 1, this only effects the index files that Solr writes. The 
write.lock files and backups are being created with a different 
replication factor. The reason for this should be that HdfsFileWriter is 
loading the defaults from the server 
(fileSystem.getServerDefaults(path)) while HdfsLockFactory and 
HdfsBackupRepository are simply using defaults, which seems to end up 
using a replication factor of 3 (and a block size of 128MB). Is this 
known? If not shall I open a JIRA for this?

regards,
Hendrik
