Jessica Cheng Mallet updated SOLR-6854:
---------------------------------------
Description:
CloudSolrServer’s cached state is not being updated for a newly created
collection if we started polling for the collection state too early and a
"down" state is cached. Requests to the newly created collection continues to
fail with "No live SolrServers available to handle this request" until the
cache is invalidated by time.
Logging on the client side reveals that while the state in ZkStateReader is
updated to "active", the cached state in CloudSolrServer remains in "down".
