Gus Heck commented on SOLR-13169:
---------------------------------
Bumping into this again... This (without replica param) succeeded, so replica
is not always required:
{code}http://localhost:8983/solr/admin/collections?action=MOVEREPLICA&collection=test&targetNode=192.168.2.171:8982_solr&fromNode=192.168.2.171:8983_solr&shard=shard1
{
"responseHeader": {
"status": 0,
"QTime": 5060
},
"success": "MOVEREPLICA action completed successfully, moved
replica=test_shard1_replica_n1 at node=192.168.2.171:8983_solr to
replica=test_shard1_replica_n5 at node=192.168.2.171:8982_solr"
}
{code}

> Key: SOLR-13169
> URL: https://issues.apache.org/jira/browse/SOLR-13169
> Project: Solr
> Issue Type: Improvement
> Components: v2 API
> Reporter: Gus Heck
> Priority: Major
>
> At a minimum required parameters should be noted equally in both places.
> Conversation with [~ab] indicates that there are also some discrepancies in
> what is and is not actually required in docs vs code. ("in MoveReplicaCmd if
> you specify “replica” then “shard” is completely ignored")
> Also in v2 it seems shard might be inferred from the URL and in that case
> it's not clear if the URL or the json takes precedence.
> From introspect:
> {code:java}
> "move-replica": {
> "type": "object",
> "documentation":
> "https://lucene.apache.org/solr/guide/collections-api.html#movereplica";,
> "description": "This command moves a replica from one
> node to a new node. In case of shared filesystems the `dataDir` and `ulogDir`
> may be reused.",

> From ref guide for V1:
> MOVEREPLICA Parameters
> collection
> The name of the collection. This parameter is required.
> shard
> The name of the shard that the replica belongs to. This parameter is required.
> replica
> The name of the replica. This parameter is required.
> sourceNode
> The name of the node that contains the replica. This parameter is required.
