Erick Erickson updated SOLR-6482:
---------------------------------
Attachment: SOLR-6482.patch
Here's a first cut at the patch, still need to add tests but this seems to work
when I tested it manually.
Its pretty simple all told, it seems like it shouldn't interfere with the "ZK
as truth" model.
> Add an onlyIfDown flag for DELETEREPLICA collections API command

> Having the DELETEREPLICA delete the index is scary for some situations,
> especially ones in which the operations people are taking more explicit
> control of the topology of their cluster. As we move towards ZK being the
> "one source of truth" and deleting replicas that then come back up, this is
> even scarier.
> I propose to have an optional flag onlyIfDown that remove the replica from
> the ZK cluster state if (and only if) the node was offline. Default value:
> false.
