serverManager.deadServers

Hi,
After I shutdown a region server, it is not among the dead servers returned
by stargate.
getClusterStatus() returns serverManager.deadServers

I am wondering under what scenario a region server is added to
serverManager.deadServers

Thanks

When a server is shutdown on the master, it is added to the deadServers list.

This is so if we somehow get a report from this region server, we know to reject it (YouAreDeadException).  That happens when an RS goes into a long GC pause, for example.
