> If the DN scrubber marks a container as UNHEALTHY, the EC Replication Manager
> logic needs to be able to deal with it. It needs to remove the unhealthy one,
> and create a new copy using EC Reconstruction.
> However we need to be careful to perhaps create the new replica before
> removing the unhealthy one. Also, if there are too many unhealthy, it would
> make the container unrecoverable, as there are not enough healthy replicas to
> try.
> The LegacyReplicationManager handles this in the handleUnstableContainer
> method, but I wonder if we would be better handling it in the
> underReplicationHandler, as it is basically a form of under replication.
> The logic to deal with it, is also going to be different from EC and Ratis.
