Is your feature request related to a problem? Please describe

  • Before migration starts, new nodes join the cluster in MIXED compatibility mode, while the migration direction remains at its default value of NONE.
  • We should handle shard allocation correctly under these conditions, based on the index settings.

Describe the solution you'd like

The following scenarios should be handled in RemoteStoreMigrationAllocationDecider.java:

  • For remote store backed indices, shards should only be allocated to remote store nodes.
  • For non remote store backed indices, shards should only be allocated to non-remote store or docrep nodes.
