Hrishikesh Gadre updated SOLR-7374:
-----------------------------------
Attachment: SOLR-7374.patch
Please find the patch attached. It includes following
- A backup repository interface and concrete implementations for local file-system and HDFS
- Ability to configure repositories via solr.xml
- Refactored the "core" level backup/restore to use this repository interface
- Unit test for HDFS integration.

> Currently when we create a backup we use SimpleFSDirectory to write the backup indexes. Similarly during a restore we open the index using FSDirectory.open .
> We should provide a param called {{directoryImpl}} or {{type}} which will be used to specify the Directory implementation to backup the index.
> Likewise during a restore you would need to specify the directory impl which was used during backup so that the index can be opened correctly.
> This param will address the problem that currently if a user is running Solr on HDFS there is no way to use the backup/restore functionality as the directory is hardcoded.
> With this one could be running Solr on a local FS but backup the index on HDFS etc.
