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.
