Forest Soup updated SOLR-7069:
------------------------------
Description:
When querying a collection with a core in "down" state, if we send the request
to the server containing the "down" core, while the server is active, it cannot
failover to the good replica of same shard on another server.
The steps to make a core "down" on an active server is:
1, delete the content of the data folder of the core
2, restart the solr server the core locates.
Then we can see the core is "down" while other cores on the same server is
still active. See attached picture.
When we issue a query to the collection, if we send the request to the server
containing the "down" core, we receive below errors:
