------------------------------------
[~dsmiley]
Preparing for first release with logchange tool, I found that this issue adds
two CHANGES.txt entries for the same JIRA, under different headings:
{code:java}
Optimizations
---------------------
* SOLR-17568: The CLI bin/solr export tool now contacts the appropriate nodes
directly for data instead of proxying through one.
(David Smiley)
Other Changes
---------------------
* SOLR-17568: SolrCloud no longer reroutes/proxies a core request to another
node if not found locally. (David Smiley) {code}

If this was not on purpose, please clean up the CHANGES file before we generate
CHANGES.md next week.
> Remove remote *core* query in SolrCloud mode

> If a SolrCloud node receives a request with a local core name (not a
> collection name), it will be handled by the local core. But it even works
> with a remote core -- it'll be forwarded to the node that has a core by that
> name. I think there's no use-case for that -- users should only reference
> collections (any node) or a core on a node where it's known to exist (on that
> node!) since it's a core not a cluster concept. This got my attention
> because the functionality requires iterating all collections. This would
> happen for any request when a collection/core is not known to the node (and
> may not exist at all). I shall remove this in Solr 10.
> There is exactly one test for this functionality --
> {{org.apache.solr.cloud.AbstractBasicDistributedZk2TestBase#addAndQueryDocs}}
