Description

MOVEREPLICA API in Solr creates NRT type replica in the target node always,
no matter what type the source replica is. This leads to an inconsistent cluster state.

MoveReplicaCmd

    ZkNodeProps addReplicasProps = new ZkNodeProps(
        COLLECTION_PROP, coll.getName(),
        SHARD_ID_PROP, slice.getName(),
        CoreAdminParams.NODE, targetNode,
        CoreAdminParams.NAME, newCoreName);
