Shalin Shekhar Mangar updated SOLR-2610:
----------------------------------------
Attachment: SOLR-2610.patch
Patch adds a boolean "deleteIndex" parameter to core unload action.
There is a close hook interface in SolrCore but it is called before the update
handler and searcher(s) are closed so it cannot be used to delete the index.
Changes:
* Changes the CloseHook interface to an abstract class with a
preClose(SolrCore) and a postClose(SolrCore) method
* Changed the usage of CloseHook in ReplicationHandler, SolrCoreTest
* CoreAdminHandler adds a closehook on receiving an unload action with
deleteIndex=true
* Added tests for the new param
Since the CloseHook is used very sparingly, I think it is fine to change it to
an abstract class but if people feel strongly against it, we can find another
way.

> Right now, one can unload a Solr Core but the index files are left behind and
> consume disk space. We should have an option to delete the index when
