Íñigo Goiri commented on HDFS-13478:
------------------------------------
I could make this part of the Membership table but I think it's better to keep
it in a separate table.
In this way, they are independent and we can keep the subcluster decommissioned
even when there is no Router heartbeating.

> Reporter: Íñigo Goiri
> Assignee: Íñigo Goiri
> Priority: Major

> We have a subcluster in our federation that is for testing and is
> missbehaving. This has a negative impact on the performance with operations
> that go to every subcluster (e.g., renewLease() or setSafeMode()).
