      Description

      Currently there are certain default actions implemented in CoreAdminHandler ( CREATE , SWAP, RELOAD , ALIAS etc.) .

      For the purpose of in-house monitoring tools that needs to interact with multiple cores at a given solr instance - we need custom handlers that has access to CoreContainer and the req, resp of the same.

      So - the proposed way of injecting handlers is as follows.

      In solr.xml - we add a new schema -

      <solr >
      <cores adminPath="/cores/admin">

      <adminActionHandler action="newaction" handlerType="com.mydomain.myclass" />
      </cores>
      </solr>

      New abstract class - CoreAdminActionRequestHandler added - that com.mydomain.myclass would need to inherit from.

      Following action handlers registered by default -

      registerCustomAdminHandler("create", new AdminCreateActionRequestHandler());
      registerCustomAdminHandler("rename", new AdminRenameActionRequestHandler());
      registerCustomAdminHandler("alias", new AdminAliasActionRequestHandler());
      registerCustomAdminHandler("unload", new AdminUnloadActionRequestHandler());
      registerCustomAdminHandler("status", new AdminStatusActionRequestHandler());
      registerCustomAdminHandler("persist", new AdminPersistActionRequestHandler());
      registerCustomAdminHandler("reload", new AdminReloadActionRequestHandler());
      registerCustomAdminHandler("swap", new AdminSwapActionRequestHandler());

      Trying to register a handler with one that already exists would result in an error ( Hence - the above mentioned defaults would not be overridden).
