> {{ECUnderReplicationHandler}} checks if current replica datanodes + potential
> replica datanodes satisfy placement policy. If they don't, the targets are
> rejected and recovery fails. While this check makes some sense, it can block
> container recovery. Since under replication is more serious than mis
> replication, we should let a new replica be reconstructed even if it doesn't
> satisfy placement policy.
> Also, we should rely on the policy to suggest a node that satisfies the
> policy - if there is none, the policy will fallback and try to suggest a node
> on a rack where the container is already present.
