[jira] [Commented] (SOLR-15258) ConfigSetService: add CRUD
operations, subsume ZkConfigManager
[ https://issues.apache.org/jira/browse/SOLR-15258?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17415179#comment-17415179 ]
Ilan Ginzburg commented on SOLR-15258:
--------------------------------------
[~nazerke] I believe I have found an issue in this code (I didn't run it but [~dsmiley] confirmed).
From {{CoreContainer.load()}}, when {{ZkContainer.initZooKeeper()}} is called, if the {{bootstrap_conf}} property is {{true}} then {{ConfigSetService.bootstrapConf()}} is called.
If cores are then discovered this in turn calls {{getConfigSetService().uploadConfig()}} on the {{CoreContainer}}.
{{CoreContainer.getConfigSetService()}} then returns the uninitialized {{coreConfigService}}, likely leading to a null pointer exception (given {{coreConfigService}} is initialized later in the {{load()}} method).

> Key: SOLR-15258
> URL: https://issues.apache.org/jira/browse/SOLR-15258
> Project: Solr
> Issue Type: Improvement
> Reporter: David Smiley
> Assignee: David Smiley
> Priority: Minor
> Fix For: main (9.0)
>
> Time Spent: 9.5h
> Remaining Estimate: 0h
>
> Increase the scope of ConfigSetService with CRUD operations and anything else so that it can be the one place to go for anything ConfigSet related. This should be easier to understand/maintain, and also improve the efficacy of the plug-ability of ConfigSetService.
> It's likely ZkConfigManager will disappear, with most of its functionality moving into CloudConfigSetService (ZK). A number of places in SolrCloud use ZkConfigManager that will change to use the ConfigSetService instead.
