[jira] [Commented] (SOLR-16305) MODIFYCOLLECTION with 'property.*' changes can't change values used in config file variables (even though they can be set during collection CREATE)
[ https://issues.apache.org/jira/browse/SOLR-16305?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17581617#comment-17581617 ]
David Smiley commented on SOLR-16305:
-------------------------------------
I think of this as an enhancement, not a bug.
I think we should put custom properties into the Collection's state.json so that ZK is the source of truth. We should also ensure to remember this in backup-restore and maybe re-index use case. The node should only have the data (updateLog + index).

> Consider a configset with a {{solrconfig.xml}} that includes a snippet like this...
> {code:java}
> <str name="param.check">${custom.prop:customDefVal}</str>
> {code}
> ...this {{custom.prop}} can be set when doing a {{CREATE}} command for a collection that uses this configset, using the {{property.*}} prefix as noted in the reg-guide...
> {quote}{{property.{_}name{_}={_}value{_}}}
> |Optional|Default: none|
> Set core property _name_ to {_}value{_}. See the section [Core Discovery|https://solr.apache.org/guide/solr/latest/configuration-guide/core-discovery.html] for details on supported properties and values.
> {quote}
> ...BUT....
> These values can *not* be changed by using the {{MODIFYCOLLECTION}} command, in spite of the ref-guide indicating that it can be used to modify custom {{property.*}} attributes...
> {quote}The attributes that can be modified are:
> * {{replicationFactor}}
> * {{collection.configName}}
> * {{readOnly}}
> * other custom properties that use a {{property.}} prefix
> See the [CREATE action|https://solr.apache.org/guide/solr/latest/deployment-guide/collection-management.html#create] section above for details on these attributes.
