the problem comes out while I'm trying to use Sharing Indexes feature to rename the each index; i set the breakpoint at ElasticsearchIndexManager line 141 and IndexManagerHolder line 92 finding out that two names are different which causes WorkQueuePerIndexSplitter line 31 indexManagerHolder.getBackendQueueProcessor( indexName ) to be Null , but i'm not sure whether or not it's an issue.
<property name="hibernate.search.com.xxx.xxx.xxx.Company.indexName" value="DefaultCompany"/>
Thank you very much for reporting this bug. I managed to reproduce it and I'm currently trying to solve it.
In the meantime, if you use annotation mapping, you should be able to override the index name with @Indexed(index = "DefaultCompany").
EDIT: fix an error in my code snippet. It's Indexed.index, not Indexed.name.
Actually the annotation way currently isn't suitable for what I need, because of that I am using Spring Configuration YAML to manage multiple environments, so I need to override the index name by different one.
Ok. The only other alternative I can see for now is programmatic mapping, which theoretically could fit your use case, but it seems a bit too much just to override an index name.
Anyway, fear not: we have a fix and it will definitely make it into 5.6.0.Final. The fix is currently undergoing review.
Okay, I've seen your code on github, I think I've got an idea to solve it, thx.
