Andrzej Bialecki created SOLR-13583:
----------------------------------------
Summary: Impossible to delete a collection with the same name as
an existing alias
Key: SOLR-13583
URL: https://issues.apache.org/jira/browse/SOLR-13583
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Affects Versions: 8.1.1, 8.1
Reporter: Andrzej Bialecki
Assignee: Andrzej Bialecki
Fix For: 8.1.2
SOLR-13262 changed the behavior of most collection admin commands so that they
always resolve aliases by default. In most cases this is desireable behavior
but it also prevents executing commands on the collections that have the same
name as an existing alias (which usually points to a different collection).
This behavior also breaks the REINDEXCOLLECTION command with
{{removeSource=true,}} which can also lead to data loss.
This issue can be resolved by adding either an opt-in or opt-out flag to the
collection admin commands that specifies whether the command should attempt
resolving the provided name as an alias first. From the point of view of ease
of use this could be an opt-out option, from the point of view of data safety
this could be an opt-in option.
