io.hfile.bloom.enabled in
Configuration serves as the kill switch in case
something goes wrong. Default = true.
io.hfile.bloom.error.rate = average false
positive rate. Default = 1%. Decrease rate by ½ (e.g. to .5%) == +1
bit per bloom entry.
io.hfile.bloom.max.fold = guaranteed minimum
fold rate. Most people should leave this alone. Default = 7, or can
collapse to at least 1/128th of original size. See the
Development Process section of the document BloomFilters
in HBase for more on what this option means.
