Description

When we invoke splitshard Collection API against a cluster with legacyCloud=false, we get the following errors:

The sub-shard replica (leader) creation fails due to:

},
STATUS: "failed",
Response: "Error CREATEing SolrCore '3M_shard1_0_replica1': non legacy mode coreNodeName missing shard=shard1_0&name=3M_shard1_0_replica1&action=CREATE&collection=3M&wt=javabin&qt=/admin/cores&async=split117278099904930&version=2"
