> In section 94.4. Bloom Filters:
>  Since HBase 0.96, row-based Bloom filters are enabled by default. (HBASE-)  --> in *HBASE-8450*
> In section 94.4.3. Configuring Server-Wide Behavior of Bloom Filters: 
> io.hfile.bloom.enabled  --> *io.storefile.bloom.enabled*  Master switch to enable Bloom filters
> io.hfile.bloom.max.fold  --> *io.storefile.bloom.max.fold*
> io.hfile.bloom.error.rate --> *io.storefile.bloom.error.rate*
> io.storefile.bloom.block.size --> *default is 128*1024 = 131072*
> These properties are probably not tuned usually, but should still be fixed in the doc.
