Jean-Daniel Cryans commented on HBASE-4199:
-------------------------------------------
I'm sorta confused by TestBlockCacheSummary.testBlockCacheSummary, you have 3
region servers but then you create a BC from StoreFile.getBlockCache that isn't
related to any RS (because the get a different conf object in
MiniHBaseCluster.init). What is it testing exactly? Do you need 3 RS btw?
You should set BlockCacheSummaryEntry's attributes to some default values
because you might end up with NPEs that are hard to debug, just a precaution
with Writables.
There's some cleanup to do too, long lines and whatnot.
