Jonathan Gray updated HBASE-4641:
---------------------------------
Attachment: HBASE-4641-v1.patch
In the HMaster constructor, makes a local copy of the passed-in Configuration
and then sets the cache size to 0.
This seems like the wrong way to do this.
It seems like the only way this happens now is on create table (because HRegion
instantiation happens in master at this time). I could set/reset the conf in
that place instead?

> 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.
