------------------------------------------------------------
{{hbase.bucketcache.size}} is the total size of the bucket cache. no?
Also a value of "percentage to total heap size" to this property should be
applicable if the buckeCache io engine is set to "heap". For ease of use, it
would be good to accept only a percentage value (float value of > 0 and < 1) if
the io engine is heap. Currently users can set a percentage or an actual size.
By forcing to a percentage, it will be in sync with the other heap allocations
like memstore and lruBlockCache configuration value and also will help avoid
users exceeding the 80% heap size limit.
