David Smiley commented on SOLR-15100:
-------------------------------------
BTW, there are a number of places in SolrCloud that assume a configSet exists
in ZooKeeper. Ideally such places will migrate to ConfigSetService where it
can be pluggable. I did an IDE find-usages on ZkConfigManager and found these
suspicious locations:
* QueryElevationComponent
* CreateCollectionCmd (getConfigName, copyDefaultConfigSetTo, getConfName )
* DeleteCollectionCmd (for auto generated configSets -- deleting)
* OverseerCollectionMessageHandler (validateConfigOrThrowSolrException)
* RestoreCmd (for backups) – line 277)
* BackupManager (uploadConfigDir downloadConfigDir)
It's debatable wether the ConfigSet API (see ConfigSetsHandler &
OverseerConfigSetMessageHandler) should assume ZK or not. I think I'd prefer
that the ConfigSetService be a suitable abstraction to handle CRUD operations
and thus reduce how far flung the related code is. I'll file a new issue.
