> HBASE-10641 introduced the ability to configure multiple sizes for the
> buckets of the BucketCache, in HBase 0.98 and newer. To configurable multiple
> bucket sizes, configure the new property
> {color:#ff0000}{{hfile.block.cache.sizes}}{color} (instead of{color:#ff0000}
> {{hfile.block.cache.size}}{color}) to a comma-separated list of block sizes,
> ordered from smallest to largest, with no spaces. The goal is to optimize the
> bucket sizes based on your data access patterns. The following example
> configures buckets of size 4096 and 8192.
> <property> <name>{color:#ff0000}hfile.block.cache.sizes{color}</name>
> <value>4096,8192</value> </property>
