Subject [jira] [Commented] (SOLR-7374) Backup/Restore should provide a param for specifying the directory implementation it should use
Date Mon, 06 Jun 2016 17:43:21 GMT

    [ https://issues.apache.org/jira/browse/SOLR-7374?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15316839#comment-15316839
] 

Mark Miller commented on SOLR-7374:
-----------------------------------

I'm try to pinpoint if this has destabilized TestReplicationHandlerBackup or if it was before.
Otherwise this is looking pretty good, just want to do a little manual testing. Anything else
would be nitpicky mostly, but perhaps more comments coming.

> 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.
