Yoann Rodière ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *updated* an issue Hibernate Search ( https://hibernate.atlassian.net/browse/HSEARCH?atlOrigin=eyJpIjoiNTg4NDc5... ) / Task ( https://hibernate.atlassian.net/browse/HSEARCH-3266?atlOrigin=eyJpIjoiNTg... ) HSEARCH-3266 ( https://hibernate.atlassian.net/browse/HSEARCH-3266?atlOrigin=eyJpIjoiNTg... ) Ensure Hibernate Search 5 configuration files will make bootstrap fail in 6 ( https://hibernate.atlassian.net/browse/HSEARCH-3266?atlOrigin=eyJpIjoiNTg... ) Change By: Yoann Rodière ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) At least one configuration property that did not exist in Search 5 should be provided explicitly by the user in order for Search 6 to bootstrap successfully. This way, we will ensure that every user migrating from Search 5 to Search 6 will think about updating his configuration. The most obvious choice would be to require users to set their backend type explicitly; the minimal configuration file would then be: {noformat} hibernate.search.backend_defaults.type = elasticsearch {noformat} Or something similar. We should add tests to be sure bootstrapping without any with Search 5 configuration properties actually fails.
