[jira] [Updated] (SOLR-12501) System Collection should use the
correct luceneMatchVersion
[ https://issues.apache.org/jira/browse/SOLR-12501?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Cassandra Targett updated SOLR-12501:
-------------------------------------
Component/s: blobstore
> System Collection should use the correct luceneMatchVersion
> -----------------------------------------------------------
>
> Key: SOLR-12501
> URL: https://issues.apache.org/jira/browse/SOLR-12501
> Project: Solr
> Issue Type: Bug
> Security Level: Public(Default Security Level. Issues are Public)
> Components: blobstore
> Reporter: Varun Thacker
> Priority: Major
>
> Whenever we create the system collection, the solrconfig is hard-coded and comes from SystemCollectionSolrConfig.java
> Here we always set the luceneMatchVersion to the latest instead of the lucene version that is being released.
> When you go to create the collection we will get this warning the logs
> {code:java}
> WARN - 2018-06-19 14:53:00.400; [c:.system s:shard1 r:core_node2 x:.system_shard1_replica_n1] org.apache.solr.core.Config; You should not use LATEST as luceneMatchVersion property: if you use this setting, and then Solr upgrades to a newer release of Lucene, sizable changes may happen. If precise back compatibility is important then you should instead explicitly specify an actual Lucene version.{code}
> The downside is if a user upgrades Solr then the new docs analysis behaviour could differ.
