Biju Nair commented on HBASE-18708:
-----------------------------------

Hi [~anoop.hbase], if off heap mode for BC is removed we don't need this trivial change.

> Currently heap allocations for RS memory structures like {{memstore}} and {{lruCache}}
are configured as percentage of total RS heap size. Since on-heap bucketCache uses RS heap,
configuring it as a percentage of heap size will improve usability. Currently this can be
configured either as a percentage of heap or a memory size in MiB and we can remove the latter
option which is applicable to external or off-heap bucketCache.
