Subject [jira] [Commented] (SOLR-3866) CoreAdmin SWAP and RENAME need fixed/defined when using SolrCloud
Date Tue, 13 Nov 2012 17:26:12 GMT

    [ https://issues.apache.org/jira/browse/SOLR-3866?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13496352#comment-13496352

Ryan Josal commented on SOLR-3866:
----------------------------------

The use case I (and it appears the author of the instigating thread for this issue: http://osdir.com/ml/solr-user.lucene.apache.org/2012-09/msg00893.html)
have for CoreAdmin SWAP is to support a backup core (on deck core) that I can rebuild the
index from scratch on.

> We need to define what the expected behavior of using the CoreAdminHandler's SWAP and
RENAME commands is if you are running in SolrCloud mode.
> At the moment, it seems to introduce a disconnect between which "collection" the SolrCore
thinks it's a part of (and what appears in the persisted solr.xml) vs what collection ZooKeeper
thinks the SolrCore(s) that were swaped/renamed are a part of.  We should either "fix" this,
or document it if it as actually consistent and intentional for low level controls, or disable
commands like SWAP/RENAME in SolrCloud mode
