-------------------------------
You are right Andrew. The message was meant to convey "Too many blocks to show in the UI without overwhelming....nothing wrong w/ your blockcache"

> If metrics calculations over blockcache contents stopped after examining hbase.ui.blockcache.by.file.max items, the UI will put up a message. However, this notion of "too many blocks" / fullness refers to structures used for calculating blockcache metrics. See BlockCacheUtil. We should improve this message so it does not leave a user the impression the blockcache may be in a bad state.
