Allow Solr to load index from arbitrary directory in dataDir and Commit point
-----------------------------------------------------------------------------

                 Key: SOLR-658
                 URL: https://issues.apache.org/jira/browse/SOLR-658
             Project: Solr
          Issue Type: Improvement
    Affects Versions: 1.3
            Reporter: Noble Paul


This is a requirement for java based Solr replication 

Usecase for arbitrary index directory:
if the slave has a corrupted index and the filesystem does not allow overwriting files in
use (NTFS) replication will fail. The solution is to copy the index from master to an alternate
directory on slave and load indexreader/indexwriter from this alternate directory.

Usecase for arbitrary commitpoint :
Replication can also provide rollback feature . The rollback should be able to mention a comitpoint
/generation so that rollback is possible.
