Ted Yu commented on HBASE-4641:
-------------------------------
I think the fact that Configuration object may be shared by both master and
region server(s) in minicluster poses limitation on this and future tasks.
We should think of changing this sharing which would never happen in production
cluster.
Once that is done, there would be no need to replicate Configuration as patch
v1 did.

> After changes in the block cache instantiation over in HBASE-4422, it looks
> like the HMaster can now end up with a block cache instantiated. Not a huge
> deal but prevents the process from shutting down properly.
