> Remove "hbase.bucketcache.percentage.in.combinedcache". It is unnecessary
> complication of block cache config. Let L1 config setup be as it is whether
> a L2 present or not, just set hfile.block.cache.size (not
> hbase.bucketcache.size * (1.0 -
> hbase.bucketcache.percentage.in.combinedcache)). For L2, let
> hbase.bucketcache.size be the actual size of the bucket cache, not
> hbase.bucketcache.size * hbase.bucketcache.percentage.in.combinedcache.
> Attached patch removes the config. and updates docs. Adds tests to confirm
> configs are as expected whether a CombinedBlockCache deploy or a strict L1+L2
> deploy.
