-----------------------------------
Summary: CloudSolrClient should not throw "Collection not found"
with an out-dated ClusterState
Key: SOLR-17153
URL: https://issues.apache.org/jira/browse/SOLR-17153
Project: Solr
Issue Type: Improvement
Security Level: Public (Default Security Level. Issues are Public)
Components: SolrJ
Reporter: David Smiley
Today, CloudSolrClient will locally fail if it's asked to send a request to a
collection that it thinks does not exist due to its local ClusterState view
being out-of-date. We shouldn't fail! And most SolrCloud tests should then
remove their waitForState calls that follow collection creation! Other stale
state matters are out-of-scope.
Proposal: CloudSolrClient shouldn't try and be too smart. Always route a
request to Solr (any node); don't presume its state is up-to-date. Maybe,
after a response is received, it can check if its state has been updated and if
not then explicitly get a new state. Or not if that's too complicated.
