]
Jan Høydahl updated SOLR-12770:
-------------------------------
Description:
For legacy master/slave clusters, there is no Zookeeper to keep track of all
the nodes and shards in the cluster. So users manage the 'shards' parameter
manually for distributed search. This issue will add the option of configuring
a list of what shards can be requested.
Users will then get an explicit error response if the request includes a shard
which is not in the preconfigured whitelist, e.g. due to a typo. I think all
shards logic is handled by HttpShardHandler already so the logic should fit
nicely in that one class, configured in {{solr.xml}}.
With SolrCloud this whitelist is auto managed to match nodes in the cluster. It
is possible to disable the whitelist feature for backward compatibility. Please
see Reference Guide chapter [Distributed
Requests|https://builds.apache.org/view/L/view/Lucene/job/Solr-reference-guide-7.7/javadoc/distributed-requests.html#configuring-the-shardhandlerfactory].
