Andr=C3=A9 Bois-Crettez commented on SOLR-3866:
------------------------------------------

I have the impression that when a CoreAdmin rename occurs, it is somehow co=
mmunicated across the whole cloud and messes up the Zk conf (I have not yet=
 been able to trace exactly what happens).

Wild guess, but what if the CoreAdmin rename is "silent" and only have an e=
ffect on the actual shard being addressed ? That means manually sending a r=
ename for each shard to properly swap a distributed collection, but it may =
be cleaner this way ?

> We need to define what the expected behavior of using the CoreAdminHandle=
r's SWAP and RENAME commands is if you are running in SolrCloud mode.
> At the moment, it seems to introduce a disconnect between which "collecti=
on" the SolrCore thinks it's a part of (and what appears in the persisted s=
olr.xml) vs what collection ZooKeeper thinks the SolrCore(s) that were swap=
ed/renamed are a part of.  We should either "fix" this, or document it if i=
t as actually consistent and intentional for low level controls, or disable=
 commands like SWAP/RENAME in SolrCloud mode
