SOLR-12823: remove clusterstate.json in Lucene/Solr 9.0 - fix TestZKPropertiesWriter
TestZKPropertiesWriter relied on removed legacy features of the SolrCloud cluster to work.
Start a MiniSolrCloudCluster (implies config set and other test resources config) and have the test use the core of a created collection.
* Remove SRL.listConfigDir (unused)
* Remove SRL.getDataDir
* Remove SRL.getCoreName
* Remove SRL.getCoreProperties
XmlConfigFile needs to be passed in the substitutableProperties
IndexSchema needs to be passed in the substitutableProperties
Remove redundant Properties from CoreContainer constructors
* Remove SRL.newAdminHandlerInstance (unused)
* Remove SRL.openSchema and openConfig
* Avoid SRL.getConfigDir
Also harmonized similar initialization logic between DIH Tika processor & ExtractingRequestHandler.
* Ensure SRL.addToClassLoader and reloadLuceneSPI are called at most once
Don't auto-load "lib" in constructor; wrong place for this logic.
* Avoid SRL.getInstancePath
Added SolrCore.getInstancePath instead
Use CoreContainer.getSolrHome instead
NodeConfig should track solrHome separate from SolrResourceLoader
* Simplify some SolrCore constructors
* Move locateSolrHome to new SolrPaths
* Move "User Files" stuff to SolrPaths
Solr tests now have a similar policy to Lucene, loopback use only. If a
test tries to resolve or connect to the internet, it will get SecurityException.
Some solr tests explicitly try to talk to dead nodes with real
networking. This is not good and asking for trouble, but use low loopback port numbers instead of
multicast addresses. The idea is that it fails faster. Move these to
constants so that stuff isn't copy-pasted everywhere, in case we have to
do something different later.
SOLR-12804: Remove static modifier from Overseer queue access.
SOLR-12896: Introduce more checks for shutdown and closed to improve clean close and shutdown. (Partial)
SOLR-12897: Introduce AlreadyClosedException to clean up silly close / shutdown logging. (Partial)
SOLR-12898: Replace cluster state polling with ZkStateReader#waitFor. (Partial)
SOLR-12923: The new AutoScaling tests are way too flaky and need special attention. (Partial)
SOLR-12932: ant test (without badapples=false) should pass easily for developers. (Partial)
SOLR-12933: Fix SolrCloud distributed commit.
