-------------------------------------
Hello [~ndimiduk]
I believe this new configuration could be quite useful, and I would really
appreciate it if you could take a look at the PR when you have some time. Your
feedback would mean a lot. Thank you in advance!

> Specifying blockcache and memcache sizes as a percentage of heap is not
> always ideal. Sometimes it's easier to specify exact values rather than
> backing into a percentage. Let's introduce new configuration settings
> (perhaps named similarly to {{hbase.bucketcache.size}}) that accept byte
> values. Even nicer would be if these settings accepted human-friendly byte
> values like {{512m}} or {{10g}}.
